Self-operated Pressure and Differencial Pressure Control Valve

The 30D01D03Y/30D01D03R self-operated pressure and differentialpressure control valve iscomposed ofthe control valve,two actuators andtwo springs for pressure setting.
It is suitable for controling differentialpressure in the pipes of non-crrosiveliquids,gases and steams.It worksaccording to the priority actionprinciple and two parameters can notbe simultaneously controlled
The main features are as follows:
1.It has the pressure balancing functionwith high sensitivity.
2.Low noise, reliable performance,free of maintenance
3.The standard modular design isadopted.
4.Various combined controls can becarried out through the assemblies.
