Product features

Zdlq / X electronic electric three-way control valve is usually divided into two forms: confluence and split flow. The combined flow valve has two inlets and one outlet. Its function is to combine the two fluids into a third fluid. The diverter valve is one inlet and two outlet, which divides one fluid into two channels, so as to achieve the mixed heating or cooling of the fluid, or the unequal flow diversion, so as to meet the requirements of various working conditions. When the nominal diameter and pressure difference are small, the combined flow valve can be used in the shunt situation. When the nominal diameter DN ≥ 80mm and the pressure difference is large, the diverter valve can only be used.

Features of electronic electric three-way regulating valve:
 
The electric three-way regulating valve is often used for two kinds of medium adjustment of heat exchanger and simple ratio adjustment. It can replace two single seat and double seat regulating valves with one set. It can also save installation pipeline, save investment and occupy small space. 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 receives unified standard signal of 0-10mA DC or 4-20mA DC to drive the valve opening corresponding to the operation signal, so as to adjust the working parameters such as pressure, flow, liquid level and temperature.
Principle of electric three-way regulating valve:

Diverter valve

Combined valve

The valve body of the electric three-way control valve is of three-way structure, i.e. one in two out (split type) and two inlet and one outlet (combined type). The three-way combined regulating valve is used to mix two kinds of fluids into the third fluid, or two kinds of the same fluid with different temperatures to mix into the same temperature fluid. The three-way diverter valve divides a fluid into two parts.
