POV-250

Pilot-Operated Pressure Relief Valve

Pilot-operated relief valve holding tight seal up to 98% of set pressure.

The POV-250 uses system pressure itself to keep the main valve closed, which lets it operate much closer to the set pressure than a spring-loaded valve before leaking. It suits installations where the normal operating pressure sits close to the relief point, or where seat tightness matters for emissions.
