Pilot Operated Safety Valve

The pilot operated safety valve consists of a main valve and a pilot valve. System pressure controls the opening and closing of the main valve through the pilot valve. It features high set pressure accuracy, stable performance, excellent tightness under normal working pressure and small blowdown. Suitable for large-diameter and high-pressure working conditions. Multiple structural and material options are available to adapt to various media. Widely adopted for overpressure protection of pressure vessels and pipelines in petroleum, chemical, natural gas and power industries.
