We offer a comprehensive range of safety

relief and relief valves for use on a wide range of media, from low pressure

valves that vent to atmosphere, to high pressure (1379 bar, 20,000 psi) piped

return valves. Typically, low pressure valves offer a pop-open style

**istic, while higher pressure valves offer

proportional or metering style operation. BiS relief valves are CE

marked to denote approval as Category IV safety accessories under the 97/23/EC

Pressure Equipment Directive. Many **s are available, including cartridge

and manifold mounted versions, and many valves are available in exotic

materials via the factory, including monel, inconel, hastelloy and titanium.
