What are Pilot Operated Safety Valves

Pilot operated safety valve (also known as pulse safety valve) is a safety valve that drives or controls the main valve by discharging medium from the pilot valve. The pilot valve itself is a standard spring-loaded safety valve. Safety valves are automatic valves, which are mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. According to the opening height of the safety valve disc, it can be divided into micro open safety valve and full open safety valve.

We focus on valves in standard and special materials as customer request.
