Electric high pressure angle control valve Feature
Electric high pressure angle control valve is a special valve for high pressure system.Electric high pressure angle control valve is composed of DDZ direct stroke electric actuator and Angle valve.Take single alternating current 220V power supply as power, accept 0 ~ 10 or mA or 4 ~ 20mA dc signal, automatically control the opening size of the control valve, and achieve continuous regulation of the pressure, flow rate, temperature, liquid level and other process parameters in the pipeline.
Electric high pressure angle control valve is widely used for automatic adjustment and remote control of production process in chemical fertilizer, petrochemical, power station, light industry, etc.

Electric high pressure angle control valve body small, light weight, valve core use top guide structure, with simple flow path, small resistance, easy to flush features.Electric high pressure angle control valve is suitable for rectangular connection, medium with high viscosity, suspension and granular media.
