Product features

The ZDLQ/X electronic electric three-way regulating valve is generally divided into two forms: converging and diverting. The converging valve is two in and one out, which is used to combine two fluids into the third fluid. The diverting valve is one in and two out, which divides one fluid into two streams, so as to achieve mixed heating or cooling of the fluid, or unequal diversion of the fluid, to meet the use requirements of various working conditions. However, confluence and diversion valves can only be selected correspondingly. When the nominal diameter and pressure difference are small, the confluence valve can be used for diversion occasions. When the nominal diameter DN ≥ 80mm and the pressure difference is large, the diversion valve can only be used.

Features of electronic electric three-way regulating valve:
 
Electric three-way regulating valve is often used for regulating two mediums of heat exchanger and simple ratio regulation. It can be used instead of two single seat and double seat regulating valves. It can also save pipeline installation, investment and space. It is composed of 3810 series or PSL series straight travel electric actuator and three-way regulating valve body, powered by power supply, and receives a unified standard signal of 0~10mA DC or 4-20mA Dc to drive the valve opening corresponding to this operating signal, so as to achieve the regulation of pressure, flow, liquid level, temperature and other working parameters.
Principle of electric three-way regulating valve:

Diverter valve
Combiner valve

The valve body of the electric three way control valve is a three-way structure, that is, one in two out (split flow type), two in one out (combined flow type). The three-way combined flow control valve is used to mix two fluids into a third fluid, or two fluids of the same type at different temperatures into fluids of the same temperature. The three-way diverter valve divides one fluid into two streams.
