Product details
Overview of Electric Three way Regulating Valve
The ZDLQ and ZDLX series electronic electric three-way regulating valves are composed of 3610L series electronic electric actuators and three-way regulating mechanisms. The electric actuator has a servo system inside, which does not require additional servo amplifiers. It has input signals and power to control operation, and the wiring is simple. The regulating mechanism has two modes of operation: merging and diverging. In some cases, it can replace two two-way valves and one three-way pipe and be widely used. Commonly used for two-phase regulation and simple proportioning adjustment in heat exchangers.
