Electric Servo Valve

Electric Servo Valve
Product Detailed
Electric Servo Valve 1.Feedback signal: III type 4~20mADC;II type0~10mADC 2.Voltage:220V, frequency:50HZ 3. -10~70(5~90)egC

Electric Servo Valve 



Electric servo valve of linear electric actuator are ASSY assembly product which combined by regulating valve and linear electric actuator that take power source of single phase 220V,50HZ as dynamic. It receives unitive standard signal 4~20mA(III type) or 0~10mA(II type) and controls valve jawopening according to signal size automatically, achieve regulation for technological parameters of temperature, pressure, liquid surface flow thereby ,be widely used in generate electricity, metallurgy, petroleum, chemical industry, light industry and boiler feedwater and so on industries.

Key Technical Parameters:

Feedback signal: III type 4~20mADC;II type0~10mADC

Power Source: Single phase voltage:220V, frequency:50HZ

Operating Environmental humidity: servo amplifier≤10~70%   regulating valve≤85%

Operating Environmental temperature: servo amplifier: 0~50°

                                regulating valve-10~70°C(-25~90°C)

Electric regulating valve is suitable for medium temperature:
