Differential pressure and flow regulator also called self-operated differential pressure control valve. It is composed of the control valve, actuator and a spring used for pressure setting. It is suitable for controlling differential pressure in the pipes of non-corrosive liquids, gases and steams. When the differential pressure rises then the control valve is closed. The main features are as follows: a. It has the pressure balancing function with high sensitivity. b. Low noise, reliable performance, free of maintenance. c. The standard modular design is adopted. d. Various combined controls can be carried out through the assemblies. www.valve-cn.com
