Chemoil Advance Technology supplies Pilot Operated Pressure Relief Valves (POPRVs) from recognized manufacturers for specialized overpressure protection in high-pressure process and pipeline systems. These valves use a pilot-control arrangement to control the operation of the main pressure-relief valve.

In a pilot-operated design, the pilot senses the pressure conditions of the protected system and controls the pressure acting on the main valve. When the system reaches the specified set pressure, the pilot initiates the opening of the main valve, allowing process fluid to discharge and relieve excess pressure.
Designed for demanding industrial applications, Chemoil Pilot Operated Pressure Relief Valves deliver superior performance, reduced leakage, and enhanced pressure control compared to conventional spring-loaded relief valves. Manufactured from premium-quality materials and compliant with international standards, they are widely used in oil & gas, petrochemical, power generation, chemical processing, LNG, and refinery industries where reliable pressure protection is essential.
