ZDLQ, ZDLX three-way regulating valves are composed of electric actuator and three-way valve regulating mechanism. There is a servo system in the electric actuator. It does not need a servo amplifier. It can be controlled by input signal and power supply. The connection is simple. The regulating mechanism has two modes of action: confluence and diversion. In some cases, it can replace two two-way valves and one three-way nozzle and is widely used. Two phase adjustment and simple ratio adjustment are often used in heat exchangers.
