We offer a *prehensive 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 characteristic, 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 options 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.
