Relief Valves - Backpressure Regulators
Fisher™ Backpressure Regulators
A backpressure regulator maintains a desired upstream pressure by varying the flow in response to changes in upstream pressure. A pressure relief valve limits pressure build-up (prevents overpressure) at its location in a pressure system. The relief valve opens to prevent a rise of internal pressure in excess of a specified value. The pressure at which the relief valve begins to open pressure is the relief pressure setting.
Relief valves and backpressure regulators are the same devices. The name is determined by the application. Fisher relief valves are not ASME safety relief valves.
- Reliable overpressure protection in the form of pop-type, direct-operated, pilot-operated, and internal relief valves
- For use in natural gas, instrument air, and process applications where venting to atmosphere is acceptable, process fluid is compatible with the soft disk, and relief pressure variations are allowable
- Other popular uses:
- Token relief/indication for small leaks
- Audible signal of an overpressure condition
- Overpressure protection against minimal/nuisance leakage
