Pilot operated pressure relief valves are used for controlling the pressure in a hydraulic system and protect its hydraulic pump and actuators from over-load. According to their functions, they can be divided into different types such as relief valve, pressure relief valve, sequence valve and unloading relief valve.
The pilot-operated safety valve is a safety protection valve that controls the opening and closing of a small pilot valve to control the opening and closing of the main valve.
When the pressure of the medium in the equipment or pipeline rises and automatically exceeds the specified value, the medium pressure in the pipeline or equipment is prevented from exceeding the specified value by discharging the medium outside the system.
Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in personal safety and equipment operation.
Enriched by our vast industrial experience in this business, we are involved in offering an enormous quality range of pilot operated pressure relief valves. We are committed to bring more profit to our customers, while the quality is always the top concern.
