PRODUCT OVERVIEW
The electric three-way confluence (shunt) regulating valve is composed of PSL series and 3810l series straight stroke electric actuators and three-way regulating valve body (it can also be equipped with other brands of straight stroke actuators). The electric actuator is an electronic integrated structure with a servo amplifier. The valve opening can be controlled by inputting the control signal (4-20mA DC or 1-5V DC) and power supply to adjust the parameters such as pressure, flow, liquid level and temperature. It has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment accuracy. The electric three-way confluence regulating valve is mainly used to mix the two fluids into the third fluid; The electric three-way shunt regulating valve is mainly used to divide a stream of fluid into two streams. The valve 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.
