The pilot-operated pressure control valve is composed of control valve, pilot and actuator, it is suitable for controlling differential pressure in the pipes of non-corrosive liquids, gases and steams, when the differential pressure rises, the control valves is closed.

The main features are as follows: 

  1. It has pressure balancing function whit high sensitivity.
  2. Low noise, reliable performance, free of maintenance.
  3. The standard modular design is adopted
  4. Various combined controls can be carried out through the assemblies.
