How to order mono-flange valvesOur part number system is made up of alphanumeric / generic code system as explained below.An example is :-

Mono Flange - needle, needle, needle. 1/4 vent & outlet ports with NPT

threads. A350 LF2 carbon steel, 1/2 nominal bore, class 150, raised face

pipe connections, fire-safe.

The part number shown below is made up using the system :-

MF - NN - 2 N L - 4 A R - FS

Socket weld and butt weld end connectors may be extended for thermal protection of the valve internals

NOTE 1: The pressure ratings quoted within our literature are maximum hydrostatic pressure ratings for the valves always consult the factory for a GA drawing before you order. Certain

options available are the products / designs of other manufacturers, Alco valves cannot accept any responsibility for these products unsuitability or failure in service.

NOTE 2: The bore sizes shown above relate to the primary and or secondary valve only not necessarily to the vent valves.

NOTE 3: It is always advisable to refer to specific product literature or contact our technical sales department when ordering valves as some of these options are available only on certain

styles of valves. Any special end connections such as compression ends or butt / socket weld may limit the rated working pressure of the valve or component supplied in accordance with the

relevant specification of design or use of that method of connection. The valve or component will still carry the maximum working pressure markings in accordance with the valve or component

design not the connection method as they vary.

General Information

Design Features

Compact and lightweight. Leak paths reduced. Designed in accordance with ASME VIII, ANSI B16.34 /

B16.5, ANSI B31.3, EEMUA 182 and API 6D. Fire-safe to BS6755 Part 2 as standard. High integrity multi-ring packings for long field life /

service life. Bubble tight metal to metal seat for positive shut off. Back sealing stems to further extend packing life.

Unique cam locking device at the body to bonnetconnection for extra safety in service where vibrationexists.

Actuating threads are above the packings to preventcontamination by the process medium.

Body to bonnet ingress seal fitted as standard to preventcrevice corrosion.

2 piece non-rotating hardened (17-4PH) tip for first timeseal and long service life.

The MF type DBB is a compact and lightweight double blockand bleed valve system. All isolation valves are designed forhigh pressure instrument and process applications. Dualoutlet connections are available to allow for the instrument tobe mounted vertically or horizontally depending on the pipeorientation. The MF offers the lowest possible number ofpotential leakage points from a process connection, through

3 valves to a static instrument such as a pressure gauge.This involves only one joint - the pipeline flange to the valvebody. It is easily understood that the benefits of this unit aremany. Manometers, pressure gauges and temperaturemeasurement devices can be easily installed reducing safetyrisks and cost. Using the MF style block & bleed or doubleblock and bleed from Alco.

Mono-flange manifolds are suitable for gauge or instrumentmounting direct to a system via a standard flange take offpoint. Various flange ratings available to suit almost anypressure rating and size within piping systems. Standardapplications include static instrumentation, pressure gauges,manometers, temperature measurement devices andpressure switches.

Due to the compact size of the MF weight savings areoptimised, therefore offshore installations, F.P.S.Os canbenefit greatly. Furthermore, this slimline format does notrequire supporting. All in all any installation requiring a safer,more compact, lightweight, cost saving pipeline instrumentsolution can take advantage of the Alco mono-flange manifoldrange.
