Why use Circulation Pressure Relief Valve?
Circulation Pressure Relief Valve is a direct-acting, spring-loaded, diaphragm-type pressure relief valve designed to help prevent excessive pressure buildup in a piping or fire protection system.
The valve automatically opens when system pressure reaches the adjusted set point and closes again as the pressure returns within the desired operating range. Its design allows operation within close pressure limits, helping maintain stable and safe system performance.
It is available in Globe Type and Angle Type configurations and can be adjusted in the field by turning the adjusting screw to change the spring load.

The Circulation Pressure Relief Valve operates automatically through a spring-loaded diaphragm mechanism.
Working Process:
- The system operates at its normal pressure.
- When pressure increases beyond the preset valve setting, the internal diaphragm mechanism responds.
- The valve opens and relieves or circulates excess pressure according to the system configuration.
- As the pressure drops back to the desired operating range, the valve closes.
- The pressure setting can be adjusted in the field by turning the adjusting screw, which changes the spring load.
