The *0D*2Y *0D*2R 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, freeof maintenance
3.The standard modular design is adopted.
4.Various combined controls can be carried out through the assemblies.
