A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire.

SILO PRESSURE RELIEF VALVE. Pressure relief valve. Meet the Silo Pressure relief Valve. Models: VCP Series. Application: Cement Silo and Flyash Silo for Readymix plants and concrete batching plants.

Pressure Sustaining Valves (PSV) sense the upstream pressure and compare it to the setpoint to determine the valve position in order to maintain a set pressure upstream. As the upstream pressure rises the valve starts to open allowing flow downstream and if it falls below the setpoint the valve will shut.

Many types of valves are required in a process plant for flow regulation or on/off purpose. Type of valve employed depends on nature of fluid, flow control required, operating pressure and temperatures as well as surround atmosphere. Here is a list of symbols for various types of valves used in process industry.
