30d01d03y/r Self Operated Pressure and Differential Pressure Control Valve

Summary
the30d01d03y30d01d03r self- operated pressure and differential pressure control valve is composed of the control valve, two actuators and two springs for pressure setting. It is suitable for controling differential pressure in the pipes of non-crrosive liquids, gases and steams .it works according to the priority action principle and two parameters can not be simultaneously controlled
the main features are as follows:
1.it has the pressure balancing function with high sensitivity.
2.lownoise, reliable performance, free of maintenance
3.the standard modular design is adopted.
4 various combined controls can be carried out through the assemblies.
