Product Description
Summary
Structural figure
TheV230D01/V231D01self-operated (after-valve) pressure control valve is Composed of the control valve, actuator And a spring used for pressure setting. It is suitable for controlling after-valve Pressure in the pipes of non-corrosive liquids, gases and steams. When the after-valve pressure rises, the control Valve is closed.
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.
