Pilot Operated Safety Relief Valve

Pilot Operated Safety Relief Valves are widely used in various industries, especially oil, gas and petrochemical. These safety valves are designed according to API 526 standard. These safety valves automatically prevent any sudden pressure increase by draining part of the incoming fluid only through fluid energy. The advantage of the pilot model compared to the spring model is its optimal and faster performance, which increases the reliability of the work.
