3.- INSPECTION ON RECEPTION AND STORAGE

3.1 All valves will be examined on reception, to ensure that they have not suffered any damages

during transport, and the supplier will immediately be informed of any damages observed.

3.2 Valves leave the factory in open position as a measure of protection and to ensure that no

foreign body can damage the ball, except fail to close actuated valves (Actuator normally in closed

position).

3.3 WARNING!

Valves will be stored under cover and protected from inclement weather conditions and foreign

bodies.

3.4 Valves will not be unpacked until they are to be definitively installed, except for purposes of

inspection. After inspection they will be packed again

4.- INSTALLATION

4.1 The handling and transporting of the valves must be carried out with extreme precaution and

using the necessary and adequate means on the basis of their size and weight, in this way avoiding any

risks to the persons that handle them.

4.2 WARNING!

Never use the wrench to hold the valve during handling, assembly or transport.

Check the condition of the valve, firstly to detect any possible damages caused during their

transport and/or handling.

Likewise inspect the inside of the valve, as well as the interior of the pipe that connects up to the

valve. It is of utmost importance that there are no foreign bodies that could damage the valve seats,

insofar as these parts are fundamental to the correct operation of the valve.


of 39

WARNING!

When it is known or assumed that the valve has to be installed at a collection point for waste,

such as welding slag, rust or scale, protective filters or screens must be placed, temporarily or

definitively (depending on the installation), upstream, before connection with the valve.

The valve must be installed in such a way that it is accessible for the necessary periodic

inspection and maintenance required guaranteeing the performance levels for which it has been

designed.

JC Standard STF & STR Series construction have been designed without fluid direction

preference – “They are Bi-directional”

The valve can be installed with the stem in any position, although it is recommended that the

installation will be done in a vertical position, with the stem upwards.

WARNING!

The valves must not support stress from the piping, the installation must be carried out

ensuring correct alignment and parallelism in order to ensure that it is not subject to any

unexpected stress.

Make sure when installing the valve that the flange seal that connects up to the valve is

correctly fitted, following the seal manufacturer’s instructions, also ensuring that it is compatible with the

circulating fluid.

Install the valve to the line using the correct size and type of coupling flanges and the

appropriate gaskets (for RF) or sealed gaskets (for RTJ). The design of the valve allows the fluid can

come from any direction.

The body of the JC Trunnion mounted 3 piece body valve will be supplied with assembly

drills machined in the cover for the assembly of the actuator. Please contact us for the location and

dimensions of these drills.

IMPORTANT!

After installation run a final check on the valve, opening and closing it to make sure that it is

working perfectly.


of 39

WARNING!

Make sure that the fluid used in cleaning operations and the way in which the cleaning is

done are compatible with the installed valve.

Having finalised the final cleaning operations prior to bringing the valve on-line, if filters have

been installed they can be removed or, on the other hand if the user considers that rust or scale

formations may be encountered, they must be left permanently in place.

¡IMPORTANT!

When ball valves are destined to end line, you should reduce the hydrostatic proof pressure of

the line to 1.1 Rating pressure.

¡IMPORTANT!

After fixing the valve, travel stops “OPEN” & “CLOSED” have to be adjusted to the actuator

taking into account the bore of the ball and the position of the key of the stem.

5.- ON-OFF SERVICE

JC Trunnion Mounted 3 piece body valves are only recommended for ON-OFF service.

They close by rotating the stem or the handwheel of the gear-box clockwise. The open and closed

exact position is determined by the radial location of the stem key with respect to the fluid passage.

Body central line. When the key slot is perpendicular to the fluid passage, the valve is closed.

Gear-boxes are marked with indication arrows.

6.- DOUBLE BLOCK & BLEED

JC Trunnion mounted 3 piece body valves are appropriate for sealing different fluids in both

ends.

The installation of a vent valve provides a safe and convenient method to check the efficiency of

the tightness of the seats of the valve, as required by the double block and bleed function.


of 39

7.- PREVENTIVE MAINTENANCE

7.1 Preventive maintenance operations essentially consist of periodic inspections to ensure that the

valve is working correctly.

7.2 Valves must be opened and closed at least once every 6 months and, should such be required

on the basis of the fluid or the application of the valve and its importance, opening and closing check

plans will have to be established for shorter periods.

7.3 The user will be responsible for establishing opening and closing plans that are adequate for the

work conditions and the fluids used!

7.4 WARNING!

Never leave the valves open or closed for a long period of time.

7.5 A very high torque increase could be due to the inclusion of foreign bodies in the seats. It is

important not to force the valve! Proceed with an inspection of the seats in order to avoid damaging the

ball.

8.- MAINTENANCE OPERATIONS

PRECAUTIONS BEFORE DISASSEMBLY!!

Make sure that the line has been closed and depressurised.

Open and close the valve several times in order to release the pressure and drain the valve

cavity.

WARNING !!

Wear protective clothing adequate for the circulating fluid. (Comply with the safety

guidelines laid down by the Company!)

The replacement of parts must be done using original JC spare parts!


of 39

The manufacturer will not be responsible for the malfunctioning of the valve if original JC

parts are not used!

Once the pressure is relieved, the valve in half-open position has to be drained at 0 psig through

the drain plug (50).

It is recommended that when it is necessary to replace the gaskets and packing, body

connector gaskets and graphite gaskets of the rest of the valve should also be replaced.

9.- REASONS FOR PARTS REPAIR OR REPLACEMENT

12.- SAFETY AND USE

According to IEC 61508-2 Annex D 1.0 Introduction

1.1 Scope This manual provides necessary requirements for meeting the IEC 61508 or IEC 61511 functional safety standards and information necessary to design, install, verify and maintain a Safety Instrumented Function (SIF) using JC valves.

1.2 Terms and Abbreviations Describe Basic Terms of Functional safety: What is functional safety, safety function, safe state, fail safe, Fail safe, fail dangerous, low demand mode etc. Typical abbreviations: - FMEDA: Failure Modes, Effects and Diagnostic Analysis - HFT: Hardware Fault Tolerance - PFDAVG: Average Probability of Failure on Demand - SFF: Safe Failure Fraction, the fraction of the overall failure rate of a device that results in either

a safe fault or a diagnosed unsafe fault. - SIF: Safety Instrumented Function, a set of equipment intended to reduce the risk due to a

specific hazard (a safety loop), Safety instrumented control/protection function - SIL: Safety Integrity Level, discrete level (one out of a possible four) for specifying the safety

integrity requirements of the safety functions to be allocated to the E/E/PE safety-related systems where Safety Integrity Level 4 has the highest level of safety integrity and Safety Integrity Level 1 has the lowest.

- DC: Diagnostic Coverage Factor (if diagnostic measures exist) - PTC: Proof Test Coverage Factor - PFH: Probability of dangerous failure per hour - PFD: Probability of dangerous failure per demand

1.3 Reference Documents

- JC Valves Product Data Sheet - Notify body report and Certificate - JC Valves Maintenance and installation instructions (This document). - Special operating Instructions :

Valves manufactured by JC Valves can be equipped with a variety of: Operating mechanisms, such as handwheel, gear, electric actuator, hydraulic actuator or pneumatic actuator. Motorized valves are supplied with the actuators installed and torque and position limits correctly adjusted. For opening the valve, handwheel must be rotated counter-clockwise. Open and close position will be done by the stop regulation devices.


of 39

Unless otherwise specified, gearing in most cases is sized to close with a maximum 35Kg rim pull on the gearing handwheel at a differential shut-off pressure equal to the class of the valve. If the actual differential pressure is known, or a different rim pull is required, this information should be specified as the gearing size may change. The information required to custom size gearing is as follows: a) Operating conditions b) Differential shut-off pressure c) Maximum allowable hand wheel rim pull d) Desired hand wheel orientation. The high speed of operations in modern industry and the necessity of making process plant operations automatic have increased the need for motor operated valves. Such applications include those where the valve: 1. Is too large or has too high a differential shut-off pressure for manual operation. 2. Is not accessible for manual operation, 3. Is part of a system requiring simultaneous operation of many valves, 4. Must be triggered form a remote location, as is often essential for emergency shut-off in hazardous areas. Actuator manufacturer’s instructions must be followed in case the valve is equipped with an actuator (electric, pneumatic or hydraulic). Torque, limit switches and additional parameters are adjusted in factory before shipment. Contact JC Valves before changing any parameters. Any actuator mounted on a JC Valve has a position indicator for indicating if the valve is open or closed. This position indicator depends on the actuator type; it can be a digital or a mechanical indicator. Generally motor operating units, as illustrated are top-mounted. Side mounted units can be supplied where deemed necessary by valves manufacturer and actuators supplier. All valves are furnished with special purpose yokes designed for the motor operating unit to be used, following ISO 5211. Electric driven motor actuators consist of a special motor, a reduction gear, and necessary control components, all contained in a weather resisting enclosure, suitable for outdoor installation. Moreover units can be supplied with all necessary contacts for local or remote indication. For hazardous locations, electric control units can also be furnished, on request, with flameproof or explosion proof enclosures, depending on specifications followed by the customer.

2.0 Product Description

The ball valve is the ideal valve for perfect sealing requirements; shutoff applications such as tie-ins, maintenance isolations, line closure, etc. JC VALVES is the reference in ball valves due to our experience, quality and customer satisfaction ratio. Around 25,000 tests have been carried out at our testing facilities and in total, more than 250.000 ball valves have been manufactured. Due to the extremely long durability of our ball valves, the end user benefits not only with quality but also with lower maintenance costs. We have a solid working knowledge about the design of ball valves and the materials needed in their construction. This has led to JC VALVES becoming not only an expert in ball valves but also a leader in this market. Significant characteristics: JC VALVES manufactures metal seated ball valves for high temperature applications and severe service applications. Special coatings can be applied for any internal part in contact with fluids, depending on the customer’s needs. JC VALVES also has an extensive and proven experience in valves for cryogenic service.

3.0 Functional Safety relevant specifications

3.1 Safety Function The JC Valves are typically used in ON/OFF services, so the safety function of a valve is to stop or allow the fluid pass through it. In an emergency situation the valve must be able to close without leakage as fast as the equipment that operate the valve can do it.

3.2 Environmental Limits - Temperatures - External pressure greater than atmospheric pressure - Wind, snow and ice - Acoustic vibration and/or vibration caused by the fluid - Shock waves - Flame - Lightening - Electromagnetic waves from 3x10^11HZ to 3x10^12 Hz. - Radio frequency (RF) electromagnetic waves from 10^4 to 3x10^12; - Environmental variations

3.3 Application Limits JC VALVES is the perfect partner for the customers who require valves for special applications such as: extremely low or extremely high temperatures, high pressure, highly corrosive applications, suspension solids with unusual temperature ranges, maximum weight capacities, unexpected issues during the process, acidic products and critical plant safety applications. We have long experience supplying valves for different projects with require special valves for offshore platforms, PTA plants, as well as plants and services with extremely corrosive environments. Our Technological Services will attend to any special requirements.


of 39

Our focus in innovation has made it possible to manufacture new high specification products for special applications such as:

Tandem gate valves for Hydrogen service. Metal seated HIPPS ball valves. Double metal seated ball valves. From cryogenic temperature to high temperature range Ball valves. Flow regulation Globe manual valves. Special dimension valves. Customized %’s of material content out of standards. Etc.

JC Valves is the most reliable supplier for the most severe requirements and conditions.

The material of constructions of a JC Valves are specified in the JC Valves Datasheets and in the main literature. It is especially important that the designer of the SIF checks for the material compatibility considering on-site chemical contaminants and fluid conditions. If the JC Valves are used outside the application limits or with incompatible materials or environment, the reliability data and predicted SIL capability becomes invalid.

3.4 Design Verification

A detailed Failure Modes, Effects and Diagnostics Analysis (FMEDA) report is available from JC Valves for this product. This report details all failure rates and failure modes as well as expected lifetime of the product. The achieved Safety Integrity Level (SIL) of an entire Safety Instrumented Function (SIF) design must be verified by the designer via calculation of PFDAVG considering the architecture, proof test interval, proof test effectiveness, any automatic diagnostics, average repair time and the specific failures rates of all equipment included in the SIF. Each subsystem must be checked to assure compliance with minimum Hardware Fault Tolerance (HFT) requirements. The failure rate data listed in the FMEDA report is only valid for the useful lifetime of the JC Valve. The failure rates will increase after this useful lifetime period has expired.

3.5 SIL Capability

JC Valves are suitable for use in a safety instrumented system up to SIL 3 A proof test has to be performed once a year in order to accomplish with the safety requirements.

3.6 General Requirements

The JC Valve will be moved to its defined safe state (closed) in relation to the specific hazard scenario. All SIS components must be operational before process start-up. The User shall verify that the JC Valve is suitable for use in safety applications by confirming the JC Valve nameplate and model number is properly marked. Personnel performing maintenance and testing on the JC Valve shall first be assessed as being competent to do so. Result from periodic proof tests shall be recorded and periodically reviewed. The JC Valve shall not be operated beyond the useful lifetime.

4.0 Installation and commissioning

4.1.- SAFETY INSTALLATION AND STORAGE - The handling of valves, both whilst they are still inside the packaging and when they have been removed from it, is to be undertaken in accordance with the Assembly & Maintenance Manual. - Check the packaging is fully secure in the event that it is to be moved. - Always use endorsed chains and mooring straps of sufficient strength for moving the valve or the crates. Make sure they are in good condition. The weight of the crates is specified on them, and the weight of the valves is indicated on the corresponding drawings. - Hold the boxes by the marked mooring points. - Never pass a valve or a crate through the air over a person. - Storing valves must be carried out according the Assembly & Maintenance Manual. - When opening the crates, be careful with packing nails. Never leave the point of a nail sticking out, remove the nail completely from the crate if necessary. Do not handle crates with bare hands are there could be splinters. - When the valve is installed at a height above the ground, follow local safety regulations on working at heights. - When the valve is welded on to the line, use suitable protection and safety equipment.
