Pressure relief valves mount between the pump and valve system to protect against overloads. A suitable pilot valve may be used to "vent" the balanced piston relief valve when the system does not require power. This venting unloads the pump through the relief valve at low pressure, avoiding energy waste and reducing operating costs.

A pressure relief valve is used to release excess pressure from a system during overpressure situations thus avoiding catastrophic failure. So, a Pressure relief valve is an important process safety device and widely used in chemical, petrochemical, power, and oil and gas industries. The pressure relief valve (PRV) is designed to open at a predefined set pressure.

The flanged, spring operated pressure relief valve is designed and manufactured as a conventional valve and a balanced bellows valve. The conversion from conventional Series JOS-E or JLTJOS-E in sizes 1" D 2" through 8" T2 10" requires only the addition of a bellows assembly and bellows tail-piece gasket. No other parts are necessary. NOTE

Re-seal pressure is defined as the downstream pressure at which the check valve closes bubble-tight. Example: For a valve with a spring having a rated cracking pressure of 25 psig (1.72 bar), the actual cracking pressure ranges between 20 and 30 psig (1.38 and 2.07 bar). The re-seal pressure range would be 16 to 20 psig (1.10 to 1.38 bar).
