Self-Operated Differential Pressure Control Valve

The 30D03Y/30D03R self-operateddifferential pressure control valve iscomposed of the control valve,actuator and a spring used forpressuresetting。
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,free of maintenance
3.The standard modular design isadopted.
4.Various combined controls can becarried out through the assemblies.
