30d02y/r Self-operated (Before-valve) Pressure Control Valve

The 30D02Y/R Self-Operated (Before-Valve) Pressure Control Valve is composed of the control valve, actuator and a spring used for pressure setting. It is suitable for controlling before- valve pressure in the pipes of non- corrosive liquids, gases and steams. When the before-valve pressure rises, the control valve is opened.

The main features are as follows:
1.It has the pressure balancing function with high sensitiity.
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.
