Electric control valve is used for power supply to drive the electric actuator to drive the valve to throttle, it is an important executive unit in the industrial automation process control instrumentation. As the industry increasingly high degree of automation, is being more and more applications in various industrial fields. Compared with the traditional pressure regulating valves,electric control valve has obvious advantages: energy saving, environmentally friendly electricsingle seat control valve, and the installation is convenient.

The electric control valve by using the received signal of industrial automation control system to drive the differential pressure regulating valve series gate change between the valve core and valve seat of the cross-sectional area of the control of the flow of media channels, temperature,pressure and other parameters, adjust the function of the realization of automation.

Electric actuator electric control valve sleeve for the integration of the electronic structure, aservo amplifier, Oda, pneumatic control valve series Harima input control signal and the power to control the valve opening degree, it can regulate the parameters of pressure, flow, liquid level,temperature and so on.

Electric single seat control valve series is suitable for strict, valve before and after the pressure is low and has certain viscosity on leakage for the occasion. Three confluence valve is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment industry.
