Pressure Relief Valves

BiS Wells offer a range of Pressure Relief Valves. These safety relief valves are CE marked and conform to category IV of the Pressure Equipment Directive (PED). Unlike our back pressure maintaining valves (BPMV’s) these valves are not designed to maintain system pressure, instead they are designed to only operate only in an emergency, where there is risk of the system becoming over pressurised and potentially dangerous.

These pressure relief valves are sprung loaded for reliability and are adjustable via a hex head screw. Depending on pressure and flow will determine which type of pressure relief valve is most suited to your application.

Our relief valves can handle pressures from 300 Psi up to 15,000 Psi. Valves are offered in Stainless Steel as standard but can be manufactured from other materials if required. Valves can be supplied with 1/4”, 3/8”, 1/2” or 3/4” ports.

Our pressure relief valves are suitable for both pneumatic and hydraulic applications, please see our overview datasheets for suitability. As standard valves are offered with Nitrile or Viton seals however please contact us for medium compatibility as other elastomeric materials can be offered.

All our pressure relief valves can be manufactured specially for Oxygen use, please contact us for more information.
