Pilot-operated Control Valve, Pressure Control Valve (PCV)
Feature
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:
- It has pressure balancing function whit high sensitivity.
- Low noise, reliable performance, free of maintenance.
- The standard modular design is adopted
- Various combined controls can be carried out through the assemblies.
