Pilot-operated (after valve) Pressure Control Valve

The 30D12Y/30D12R pilot-operated(after valve) pressure control valve iscomposed of the control valve, pilotand actuator.
It is suitable for controling differentialpressure in the pipes of non-crrosiveliquids,gases and steams.when thediferential pressure rises,the controlvalve is closed
The main features are as follows:
1.It has the pressure balancing functionwith high sensitivity.
2.Low noise, reliable performance, freeof maintenance
3.The standard modular design is adopted.
4.High control precision
