Application of Directive 97/23/EC of the European Parliament

and of the Council, of 29 May 1997, concerning pressure

equipment towards Castel refrigeration products

Maximum / minimum allowable

temperature (TS):

the maximum/minimum temperatures for

which the equipment is designed, as

specified by the manufacturer

Volume (V): the internal volume of a

chamber, including the volume of nozzles to

the first connection or weld and excluding

the volume of permanent internal parts.

Nominal size (DN): numerical designation

of size, which is common to all components

in a piping system. Fluids: gases, liquids and vapours in pure

phase as well as mixture thereof.

Pressure equipments referred to in Article 3 are

classified by categories in accordance with

Annex II, according to ascending level of

hazard, on the basis of:

State of the fluid

Danger classification of the fluid

Type of equipment

Dimensions and energetic potential:

V, DN, PS, PS x V, PS x DNand must satisfy the Essential Safety

Requirement set out in Annex I of PED.

Pressure equipments below or equal to the

limits in Article 3, sections 1.1, 1.2 and 1.3

and section 2, must not satisfy the Essential

Safety Requirement set out in Annex I. They

must be designed and manufactured in

accordance with the sound engineering practice

of a Member State in order to ensure safe use

(Article 3, Section 3).

In the tables of general characteristics,

collected in this Handbook, its showed the riskcategory in which every product is classified.

In Article 9 of PED the fluids are classified,

according to their hazard, into two groups:

The Directive 97/23/EC (PED) applies

to the design, manufacture and conformity

assessment of pressure equipment

and assemblies with a maximum allowable

pressure PS greater than 0,5 bar with

the exception of the possibilities listed

in Article 1, Section 3 of the same

Directive.

Since 30 May 2002 the Directive

has become mandatory and,

in the Member States of European Community,

it has been possible to placeon the market only pressure equipments

CE marked according to PED.

For the purposes of the Directive see the

following definitions, used in this Handbook

too:

Pressure equipment: vessels, piping,

safety accessories, and pressure

accessories

Vessel: a housing designed and built to

contain fluids under pressure.

Piping: piping components intended for thetransport of fluids, when connected together

2. Do not contain hexavalent chromium, used for

the surface treatments (yellow zinc plating) of

steel parts. Castel Company has removed the

yellow zinc plating treatments from all its

products, before the end of 2005, and has

chosen:

other surface treatments containing trivalent

chromium instead of hexavalent chromium.

where possible, other materials which dont

need surface treatments.

3. Contain lead as an alloying element in steel,

aluminium and copper alloys within the

accepted limits according to the Annex of

RoHS Directive.

The purpose of Directive 2002/95/EC (RoHS

THE Kv FACTOR

Table 1 shows refrigeration capacity values

with unit Kv related to the nominal working

conditions specified in Table 2.

Appropriate corrective coefficients may be

calculated taking the values shown from Table

3 to Table 8 as a basis; this will make it

possible to predict actual working conditions.

As a result:

Liquid line:

Q = Kv Q1 L1 L2 Suction line

Q = Kv Q1 S1 S2 Hot gas line

Q = Kv Q1 H1 H2

since:

Q = required refrigeration capacity [kW];

Kv = characteristic valve coefficient [m3/h];

Q1 = reference refrigeration capacity [kW]

(Table 1).

L1 S1 H1 = are correction factors of the

refrigeration capacity in the presence of

operating temperatures different from reference

conditions.

L2 S2 H2 = are correction factors of the

refrigeration capacity for pressure drops

different from reference conditions.

The correct sizing of tubes and components of

a refrigerating system is of the utmost

importance for all kinds of plants; oversizing

and undersizing are both to be avoided since

they are equally hazardous for the correct

operation of the system.

The correct selection of a component is based

on the knowledge of the relationship between

capacity and pressure drop through that

component. For this purpose, EN 60534-1,

EN 60534-2-1 and EN 60534-2-3 standards

require manufacturers to specify the Kv

coefficient for every product.

The Kv factor is defined as the cold water

flow (volumic mass = 1000 kg/m3) in

m3/h resulting in a 1 bar pressure drop

with a completely open valve.

This definition applies to all products described

in this handbook.

The merely physical meaning, this coefficient

precisely defines the fluid-dynamic and

construction characteristics of the product, so

that, with the addition of other parameters

more closely related to the nature and

conditions of the fluid under consideration, thecapacity/pressure drop ratio may be precisely

determined.

Castel provides appropriate tables for the most

commonly used refrigerants in typical plant

working conditions in order to help engineers in

the correct selection of its products.

diaphragm assembly by 1.5 meter length of

capillary tubing, which transmits bulb pressure

to the top of the valves diaphragm. The

sensing bulb pressure is a function of thetemperature of the thermostatic charge that is

the substance within the bulb.

The body is made from forged brass with

connection in angle configuration. The

interchangeable orifice assembly can be

replaced through the inlet connection. A steel

rod, inside the body, transfers the diaphragm

movement to the plug inside the orifice

assembly. When the thermostatic charge

pressure increases, the diaphragm will be

deflected downward transferring this motion to

the plug, which lifts from seat and allows the

liquid passing through orifice. A spring opposes

the force underneath the diaphragm and the

side spindle can adjust its tension. Static

superheat increases by turning the side spindle

clockwise and decreased by turning the spindle

counter clockwise.

The thermostatic element is hardly connected

by brazing to the forged brass body to avoid any

leakage.

The body assembly can be supplied with

internal or external equalizer; both types can

also be supplied either with flare connections

or with solder connections (outlet and externalequalizer if present).

The nuts for flare connection type and the inlet-

APPLICATION

Castel thermostatic expansion valves series 22

regulate the flow of refrigerant liquid intoevaporators; the liquid injection is controlled by

the refrigerant superheat.

The new Castel 22 series are designed to

work with interchangeable orifice assembly, to

provide flexibility in selection of capacities, and

can be used in a wide range of applications as

listed below:

Refrigeration systems (display cases in

supermarkets, freezers, ice cream and ice

maker machines, transport refrigeration etc).

Air conditioning systems

Heat pump systems Liquid chillers

which use refrigerant fluids proper to the Group

II (as defined in Article 9, Section 2.2, of

Directive 97/23/EC and referred to in Directive

67/548/EEC).

OPERATION

Castel thermostatic expansion valves acts as

throttle device between the high pressure and

the low pressure sides of refrigeration systems

and ensure that the rate of refrigerant flow into

the evaporator exactly matches the rate of

evaporation of liquid refrigerant in the

evaporator. If the actual superheat is higher

than the set point the valve feeds the

evaporator with more liquid refrigerant, if the

actual superheat is lower than the set point the

valve decreases the flow of liquid refrigerant to

the evaporator. Thus the evaporator is fully

utilized and no liquid refrigerant may reach the

compressor.

CONSTRUCTION

Castel thermostatic expansion valve series 22

is made up of two parts that must work

together: the first is the body, which is the

actuator of the regulator, and the second is the

orifice, which contains the valve and attends

the expansion of the refrigerating fluid.

Body assembly: two parts make it up: the

thermostatic (power) element and the body with

its inner elements.The thermostatic element is the motor of the

valve; a sensing bulb is connected to the

charge cannot incorporate MOP functions.

Gas charge: the behaviour of valves with gas

charge will be determined by the lowest

temperature at any part of the expansion valve

(thermostatic element, capillary tube or bulb). If

any parts other than the bulb are subjected tothe lowest temperature, malfunction of

expansion valve may occur (charge migration).

Castel thermostatic expansion valves with gas

charge always feature MOP functions and

include ballasted bulb. Ballast in the bulb has a

damping effect on the valve regulation and

leads to slow opening and fast closure of the

valve.

MOP (Maximum Operating Pressure): this

functionality limits the evaporator pressure to a

maximum value to protect the compressor from

the overload condition (Motor Overload

Protection). MOP is the evaporating pressure at

which the expansion valve will throttle liquid

injection into the evaporator and thus prevent

the evaporating pressure from rising. Expansion

valve operates as superheat control in normal

working range and operates as pressure

regulator within MOP range. The MOP point will

change if the factory superheat setting of the

expansion valve is changed. Superheat

adjustments influence the MOP point as

following:

increase of superheatdecrease of MOP

decrease of superheat

increase of MOP

Superheat: this is the controlling parameter of

the expansion valve. Superheat, measured at

the evaporator outlet, is defined as the

difference between actual bulb temperature and

the evaporating temperature, deduce from

evaporator pressure. In order to prevent liquid

refrigerant from entering the compressor, a

certain minimum superheat must bemaintained. In expansion valve operation the

following terms are used:

Static superheat: its the superheat above

that the valve will begin to open. Castel

thermo expansion valves are factory preset

at the following values:

5 C for Castel valves without MOP

4 C for Castel valves with MOP

with nominal operating conditions (see table 2)

Opening superheat: its the superheat above

the static one required to produce a given

valve capacity Operating superheat: its the sum of static

and opening superheat

brazing adapter for solder connection type can

be ordered separately.

Every body assembly is supplied with a strap,

code G9150/R61 that allows fixing the bulb to

the pipe. This code can be ordered separately

too, as repair kit.

The main part of body assembly are made with

the following materials: stainless steel for bulb, capillary tubing,

diaphragm casing, diaphragm and rod

hot forged brass EN 12420 CW 617N for

body

brass EN 12164 CW 614N for superheat

setting spindle and spring holder

steel DIN 17223-1 for spring

copper tube EN 12735-1 Cu DHP for solder

connection

Orifice assembly: interchangeable orifice

assembly provide a wide range of capacity from

0,5 up to 15,5 kW (nominal capacity with R22).

The external cartridge contains the following

elements: housing, plug (metering device), seat,

spring and strainer. The rigid design of orifice

assembly and its internal components make

sure that plug and seat will withstand all types

of critical operations (liquid hammering,

cavitation, sudden variation of pressure and

temperature contaminants). The spring holds

the plug firmly to the seat to ensure the

minimum leakage through the valve; for positive

shut-off, the installation of a solenoid valve isrequired. Orifice assemblies are available in

these two solutions:

with conical flanged strainer, for valves with

SAE Flare threaded connections.

with flat flanged strainer, for valves with ODS

solder connections, to use with adapter

series 2271.

Orifice assemblies strainers can be cleaned or

exchanged, in this last case its possible to

order separately the following two types of

strainers.

strainer 2290 for valves with SAE Flarethreaded connections.

strainer 2290/S for valves with ODS solder

connections.

THERMOSTATIC CHARGES

Liquid charge: the behaviour of valves with

liquid charge is exclusively determined by

temperature changes at the bulb and not

subject to any cross-ambient interference. Theyfeature a fast response time and thus react

quickly in the control circuit. Castel

thermostatic expansion valves with liquid

Subcooling: its defined as the difference

between the condensing temperature (deduced

from condensing pressure) and the actual

temperature at inlet valve. Subcooling generally

increases the capacity of refrigeration system

and may be accounted for when dimensioning

an expansion valve. Depending on system

design, subcooling may be necessary to

prevent flash gas from forming in the liquid line.If flash gas forms in the liquid line, the capacity

of expansion valve will be greatly reduced. All

capacity tables, in this chapter, are calculated

for a subcooling value of 4 C; if the actual

subcooling is higher than 4 C the valve

capacity comes from evaporator capacity

divided by the correction factor shown in the

tables below every capacity table.

Step 4

Select a thermostatic charge. Chose the type of

charge, liquid without MOP or gas with MOP, and

the temperature range, normal temperature or low

temperature.

Step 5

Determine if external equalizer is required.

External equalizer is always required if a

distributor is used or if there is an appreciable

difference in pressure from the valve outlet to the

bulb location. Finally determine the type of

connections and their sizes.

Step 6

Order the required componentsIf SAE Flare connections you have to order the

following two parts:

- Body assembly (see tabs 1a/1b)- Orifice assembly, completed with strainer (see

tab 2)

If ODS connections you have to order the following

three parts:

- Body assembly (see tabs 1a/1b)

- Orifice assembly, completed with strainer

(see tab 2)

- Solder adapter (see tab. 3)

SELECTION

To correctly select a thermo expansion valve on a

refrigerating system, the following design

conditions must be available:

Type of refrigerant

Evaporator capacity, Qe

Evaporating temperature/pressure, Te/ peLowest possible condensing temperature/

pressure, Tc/ pcLiquid refrigerant temperature, TlPressure drop in the liquid line, distributor and

evaporator, p

The following procedure helps to select the correct

valve for the system.

Step 1

Determine the pressure drop across the valve.

The pressure drop is calculated by the formula:

where:

Pc = condensing pressure

Pe = evaporating pressure

p = sum of pressure drops in the liquid line,

distributor and evaporator

Step 2

Determine required valve capacity. Use the

evaporating capacity Qe to select the requiredvalve size at a given evaporating temperature. If

necessary, correct the evaporator capacity for

subcooling. Subcooling liquid refrigerant entering

the evaporator increase the evaporator capacity,

so that a smaller valve may be required.

The subcooling is calculated by the formula:

From the subcooling corrector factor table find the

appropriate corrector factor Fsub corresponding tothe Tsub calculated and determine the required

valve capacity by the formula:

Step 3

Determine required orifice size. Use the pressure

drop across the valve, the evaporating

temperature and the calculated evaporator

capacity to select the corresponding orifice size

from the capacity table corresponding to the

PWM SOLENOID EXPANSION VALVE WITHINTERCHANGEABLE ORIFICE

APPLICATION

Solenoid expansion valve Castel type 2028

regulates the refrigerant flow into theevaporator by modulating the opening time

phase of the plug and so permitting a wide

range of power.

This valve must be used with a coil type HM4

(see table 2), controlled by an electronic

regulator device (not supplied by Castel).

This valve is most frequently used in

refrigeration systems, in particular refrigerated

cabinets in the supermarket, which use

refrigerant fluids proper to the Group II (as

defined in Article 9, Section 2.2 of Directive

97/23/CE, and referred in Directive67/548/CE).

OPERATION

Valve type 2028 is a lamination device that

receives liquid from the condenser and injects

it into the evaporator, operating the necessary

pressure drop across the expansion orifice.

Its an ON/OFF valve that must be regulated

with the Pulse Width Modulation (PWM)

method and it can be actuated by a very simple

electronic controller. In according to the PWM

method, the evaporator refrigerant capacity QT,

required in a fixed period T, is delivered by

the valve in a time interval t, shorter than

T. During the period t the valve opens and

permits maximum flow (ON phase); in the

remaining period T-t the valve closes with no

flow (OFF phase).

For an effective PWM regulation, the valve must

be sized in such a way that in the hardest

conditions of the system, the orifice of the

valve is big enough to deliver the refrigerant

requested; in these extreme conditions the

valve will last opened for the entire period T.

The use of an electronic regulator allows a

more accurate metering of the refrigerant

reaching a greater efficiency (and then a

sensible decrement of the machinery

management costs) and a faster response to

the variations of the evaporation load.

CONSTRUCTION

Valve is supplied complete with its orifice; there

are seven different orifices corresponding toseven different evaporator capacities , that

increase passing from orifice 01 to orifice 07.

The last two numbers in the code identify what

size of orifice has been mounted on the valve

into the factory; for example the code

2028/3S02 identifies a valve with 3/8 solder

connections, size 02 orifice. The orifices are

interchangeable and can be mounted even if

the valve is soldered on the system; in this

case use the corresponding spare parts kit, in

according to table 3.

The main parts of the valves are made with the

following materials:

Hot forged brass EN 12420 CW 617N for

body and the housing pipe of the mobile plug

Copper tube EN 12735-1 Cu-DHP for solder

connections

Austenitic stainless steel EN 10088-3

1.4301 for the filter

Ferritic stainless steel EN 10088-3 1.4105

for mobile and fixed plugs

Austenitic stainless steel EN 10088-3

1.4305 for orifices

Chloroprene rubber (CR) for outlet seal

gaskets

P.T.F.E. for seat gaskets

COILS AND CONNECTORS

Coils type HM4 must be mounted on these

valves. Table 2 presents the most important

characteristics of coils and corresponding

connectors. For further technical characteristics

about HM4 coils and their connectors see to

the solenoid valve chapter.

SELECTION

To correctly select a solenoid expansion valve

on a refrigerating system, the following design

conditions must be available:

Type of refrigerant

Evaporator capacity, Qe Evaporating temperature/pressure, Te/ pe Lowest possible condensing

temperature/pressure, Tc/ pc Liquid refrigerant temperature, Tl Pressure drop in the liquid line, distributor

and evaporator, p

Nominal capacities are referred to:

Evaporating temperature Tevap = +5C

Condensating temperature Tcond = +32C

inlet temperature of liquid Tliq = +28C

The following procedure helps to select the

correct valve for the system.

Step 1

Determine the pressure drop across the valve.

The pressure drop is calculated by the formula:

( )pppp ectot +=

where:

Pc = condensing pressure

Pe = evaporating pressure

p = sum of pressure drops in the liquid line,

distributor and evaporator

Step 2

Subcooling correction. Use the evaporating

capacity Qe to select the required valve size ata given evaporating temperature. If necessary,

a given evaporating temperature. If necessary,

correct the evaporator capacity for subcooling.

Subcooling liquid refrigerant entering the

evaporator increase the evaporator capacity, so

that a smaller valve may be required. The

subcooling is calculated by the formula:

From the subcooling corrector factor table find

the appropriate corrector factor Fsubcorresponding to the !Tsub calculated and

determine the required valve capacity by the

formula:

Qsub = Fsub . Qe

Step 3

Application correction. To obtain a correct

regulation with this valve, is necessary to

oversize it so its closing period is between the

25% and the 50% of the total period T of the

regulator. The correct choice of this closing

period depends on the application, that can

have peaks of load, and on the criterion used by

the electronic regulator.

Generally, anyway, this correcting factor Fev is

str ict ly dependent by the evaporat ion

temperature so it be assumed that Fev = 1.25

for Tev >= -15C and Fev = 1.50 for Tev

cover;

chloroprene rubber (CR) for outlet seal

gaskets;

P.T.F.E. for seat gaskets.

INSTALLATION

The valves can be installed in all sections of a

refrigerating system, in compliance with the

limits and capacities indicated in Tables 3 and 6.

Tables 1 and 4 show the following functional

characteristics of a solenoid valve:

PS;

TS;

Kv factor;

minimum Opening Pressure Differential

(minOPD), that is the minimum pressure

differential between inlet and outlet at which

a solenoid valve, pilot operated, can open

and stay opened;

maximum Opening Pressure Differential

(MOPD according to ARI STANDARD 760:

2001), that is the maximum pressure

differential between inlet and outlet at which

a solenoid valve, pilot operated, can open.

Before connecting the valve to the pipe it is

advisable to make sure that the refrigerating

system is clean. In fact the valves with P.T.F.E.gaskets are particularly sensitive to dirt and

debris.

Furthermore check that the flow direction in the

pipe corresponds to the arrow stamped on the

body of the valve.

All valves can be mounted in whatever position

except with the coil pointing downwards.

The brazing of valves with solder connections

should be carried out with care, using a low

melting point filler material. It is not necessary

to disassemble the valves before brazing but

its important to avoid direct contact betweenthe torch flame and the valve body, which could

be damaged and compromise the proper

functioning of the valve.

Before connecting a valve to the electrical

system, be sure that the line voltage and

frequency correspond to the values marked on

the coil.

The NO valves have been designed to work only

with direct current coils.

To use them in applications with 220/230 VAC

suplly its necessary to mate the NO valve with

the following components:Coil 9120/RD6 +

Connector/ Rectifier 9150/R45

APPLICATIONS

The solenoid valves, shown in this chapter, are

classified Pressure accessories in the senseof the Pressure Equipment Directive 97/23/EC,

Article 1, Section 2.1.4 and are subject of

Article 3, Section 1.3 of the same Directive.

They are designed for installation on

commercial refrigerating systems and on civil

and industrial conditioning plants, which use

refrigerant fluids proper to the Group II (as

defined in Article 9, Section 2.2 of Directive

97/23/EC and referred to in Directive

67/548/EEC).

OPERATION

The valves series 1020; 1028; 1050; 1058;

1059; 1064; 1068; 1070; 1078; 1079; 1090;

1098; 1099 are normally closed.

NC = when the coil is de-energised the plunger

stops the refrigerant flow.

The valves series 1150; 1158; 1164; 1168;

1170; 1178;1190; 1198 are normally open.

NO = when the coil is energised the plunger

stops the refrigerant flow.

The valves series 1020 and 1028 are direct

acting, while the valves of all the other series

are pilot operated, with diaphragm or piston.

The NC valves are supplied either without coil

(S type) or with coil (example: A6 type with coil

HM2220 Vac).

The NO valves are supplied only without coil (S

type).

N.B.: the NO valve visually differs from the

corresponding NC model by means of the red

ring installed below the yellow nut that fastens

the coil.

CONSTRUCTION

The main parts of the valves are made with the

following materials:

hot forged brass EN 12420 CW 617N for

body and cover;

copper tube EN 12735-1 Cu-DHP for solder

connections;

austenitic stainless steel EN 10088-2

1.4303 for enclosure where the plunger

moves;

ferritic stainless steel EN 10088-3 1.4105

for plunger:

austenitic stainless steel EN ISO 3506 A2-70 for tightening screws between body and
