Electric three-way regulating valve

Composed of PSL series and 3810 series linear electric actuators and three-way regulating valve body. (Also available with other brands of linear actuators). The electric actuator is an electronic integrated structure with a servo amplifier. The input control signal (4-20mADCor1-5VDC) and power supply can control the opening of the valve to achieve the adjustment of pressure, flow, liquid level, temperature and other parameters. Electric three-way regulating valve has the characteristics of sensitive operation, simple connection, large flow, small size and high adjustment accuracy. Control accuracy and characteristics can significantly improve the DKZ type. Electric three-way regulating valve has the advantages of high precision, stable and reliable operation. Electric three-way confluence regulating valve is mainly used to mix the two fluids into a third fluid; the electric three-way diversion regulating valve is mainly used to divide a fluid into two fluids. Electric three-way regulating valve products can replace two single- and two-seat regulating valves that are mutually switching, used for the adjustment and control of liquid, gas, steam and other media.
