Amal metal flame arresters are safety devices designed to stop the propagation or spread of flames through flammable gases or vapour mixtures in pipelines. They prevent flames from entering or leaving the plant and can confine flame propagation to within certain equipment.

BAILEY
Wherever demanding applications exist you will find Bailey valves, from industrial and commercial to domestic and fire fighting. Bailey valves are used in the construction of hotels, high-rise buildings, hospitals, textile, paper and steel mills, rubber, food, drink, chemical and pharmaceutical processes, off-shore oil and gas platforms, floating production storage and off-loading (FPSO) vessels. In fact, anywhere boilers, compressors or pumps produce high-pressure service media for use on multiple low-pressure applications.
A policy of continuous improvement assures that Bailey valves will always meet current legislative requirements and of course provide exceptional reliability and performance. Bailey’s design service can help to specify the most appropriate size and type of valve for any specific application, with the ability to include special modifications where necessary.
G4 Pilot Pressure Reducing Valves
Pilot operated valves provide very close accuracy of pressure control, and due to their high flow rates, pilot valves will often be smaller than the comparable direct acting valve.
2042
The 2042 is a screwed bronze pilot operated pressure reducing valve. It provides extremely accurate levels of pressure regulation for steam, air and industrial gas applications.
2043
The 2043 is a flanged bronze pilot operated pressure reducing valve. It provides extremely accurate levels of pressure regulation for steam, air and industrial gas applications.
2044
The 2044 G4 pilot operated pressure reducing valve provides extremely accurate levels of pressure regulation for steam, air and industrial gas applications. It will maintain a constant outlet pressure irrespective of variations in the inlet pressure or demand from the system.
2045
The 2045 is a flanged carbon steel (bronze top) pilot operated pressure reducing valve. It provides extremely accurate levels of pressure regulation for steam, air and industrial gas applications.
2046
The 2046 G4 pilot operated pressure reducing valve provides extremely accurate levels of pressure regulation for steam, air and industrial gas applications.
Low Pressure Top
The standard G4 pilot top can reduce pressures down to 0.35 Barg (5 Psig). For pressures below this, a bronze low pressure pilot top can be fitted in place of the standard top, suitable for outlet pressures from 0.07 to 0.35 Barg (1 to 5 Psig).
DA Series Pressure Reducing Valves
In a direct acting pressure reducing valve, the controlled pressure acts directly through a diaphragm or piston on an imposing force from a compressed helical spring. The construction is simple and robust.
Class T
The Class T balanced direct acting pressure regulator is designed for use on installations that have varying inlet pressures and capacities, and require positive shut-off under “no flow” conditions. The standard valve is suitable for controlling air, gas and water Alternative seals and diaphragms need to be fitted for oil duty.
C10
The C10 balanced pressure reducing valve range is designed for use on water/air (gas) applications and for installations which have varying inlet pressures and capacities. It is particularly suitable where positive shut-off is required under ‘no flow’ conditions and where compact size and economy are essential.
700 Series Safety Relief Valves
Safety relief valves should be used on any closed vessel or system in which pressure, other than atmospheric or the design pressure, of the system can be exceeded.
707
The Bailey 707 Safety Relief Valve encompasses a top guided design, combining an unobstructed seat bore with high lift capability. This bronze bodied valve can be supplied with a resilient or metal trim with a choice of screwed and flanged connections.
716
The 716 Safety Relief Valve combines a top guided unobstructed seat bore with full lift capability to provide maximum discharge capability. Fitted with a test lever for inline safety checking, or alternatively with a sealed dome for service conditions requiring a pressure tight seal on
the discharge side.
716H
The 716H safety relief valve is a high pressure version of the popular 716 valve.
716T
The 716T is the ultimate solution to hot water system protection, it protects unvented hot water systems, against both excess pressure and excess temperature. Increasing pressure is sensed by the spring, which automatically opens the relief valve at the pre-set pressure and the integral probe independently monitors increases in temperature, safely opening the relief valve between 90°C and 95°C.
746
The 746 Safety Relief Valve incorporates a freely pivoting disc, which ensures correct alignment with the nozzle. The combination of top guiding, unobstructed seat bore and full lift capability ensures the highest possible discharge rate thus maximum plant protection.
756
The 756 Safety Valve combines a top piston guided valve and an unobstructed seat bore with a full lift capability, giving maximum discharge capacity. The design incorporates an adjustable blowdown ring. A freely pivoting disc and precision lapped stainless steel trim gives positive re-seating for steam duty. As standard the 756 is fitted with a test lever for inline testing. Ideally suited to applications on steam boilers and pipelines where blowdown tolerances are critical.
766
The 766 Safety Valve is a double spring high lift valve with high discharge capacity. The top guided piston design incorporates an adjustable blowdown ring. A freely pivoting disc and precision lapped stainless steel trim gives positive re-seating for steam duty. Fitted as standard with test lever for inline testing. Ideally suited to applications on steam boilers and
pipelines where blowdown tolerances are critical.
776
The 776 Safety Relief Valve is designed for cryogenic duty down to -196°C. The valve combines a full liftdesign and top guided construction with an unobstructed seat bore to provide maximum discharge capacity.
480/485/490 Relief Valves
This spring operated liquid relief valve has a cartridge type assembly which can be withdrawn from the body without disturbing the spring setting and hence relieving pressure. This allows the seating surfaces to be cleaned without the need to reset the valve.
480
This spring operated liquid relief valve has a cartridge type assembly which can be withdrawn from the body without disturbing the spring setting and hence relieving pressure.
485
485 is bronze with a renewable stainless steel seat and disc. They can also be used as a relief or combined relief and by-pass valve and can be modified to operate as an integral pump by-pass relief valve.
490
490 is all stainless steel. The inlet and outlet connections are screwed and a pressure tight screw on dome prevents leakage through the pressure adjustment assembly.
616D Safety Valves
The type 616D is a spring operated high capacity safety valve for low-pressure air applications. It is specially designed to give overpressure protection of positive displacement air blowers and associated tanks or pressure vessels.
616D
The 616D is designed to deliver precise relieving and re-seating pressures while the protected open discharge gives downward flow. The non-stick seating surfaces give positive shut-off and freedom from sticking, whilst the mixture of aluminium and gunmetal make it light but very robust. Typically used on blowers or bulk transfer road/rail transport vehicles.
