Features of electronic electric three-way regulating valve:
Electric three-way regulating valves are often used for regulating two media in heat exchangers and for simple ratio adjustment. One can replace two single-seat or double-seat regulating valves. It can also save the installation of pipelines, investment and space. Small. It is composed of 3810 series or PSL series straight-stroke electric actuator and three-way regulating valve body. It is powered by power supply and accepts a unified standard signal of 0~10mA DC or 4-20mA DC to drive the valve opening corresponding to this operating signal to achieve Adjustment of pressure, flow, liquid level, temperature and other industrial parameters.

Principle of electric three-way regulating valve:
|
diverter valve
|
combining valve
|
The valve body of the electric three-way regulating valve has a three-way structure, that is, one in and two out (splitting type), two in and one out (merging type). The three-way converging regulating valve is used to mix two fluids into a third fluid, or Two fluids of the same type at different temperatures are mixed to form a fluid of the same temperature. The three-way diverter valve divides one fluid into two fluids.
