PRODUCT OVERVIEW
Electronic electric three-way regulating valve is composed of PSL series and 361l series straight stroke electric actuators and low flow resistance straight through single seat valve (it can also be equipped with other brands of straight stroke actuators). The electric actuator is an electronic integrated structure without additional servo amplifier. The valve opening can be controlled by inputting control signal (4-20mA DC or 1-5V DC) and power supply. It is commonly used for two-phase regulation and simple proportioning regulation of heat exchanger. It has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment accuracy. The product can replace two single and double seat regulating valves which are mutually switched, and is used for the regulation and control of liquid, gas, steam and other media.
