Product Description

Summary
The 30D01D03Y/30D01D03R 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 controlling differential pressure in the pipes of non‑corrosive 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.Low noise, reliable performance, free of maintenance
3.The standard modular design is adopted.
4.Various combined controls can be carried out through the assemblies.
