Product details

Product Overview

ZDLQ electronic three-way merging control valve and ZDLX electronic three-way diversion control valve are composed of PS series and 3610 series linear electric actuators and low flow resistance straight through single seat valves. (It can also be paired with other brands of direct travel actuators). The electric actuator is an electronic integrated structure with a servo amplifier inside. By inputting control signals (4-20mADC or 1-5VDC) and power supply, the valve opening can be controlled to adjust working parameters such as pressure, flow rate, liquid level, and temperature. It has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high adjustment accuracy. The control accuracy and performance are significantly improved compared to the DKZ type.
The electronic electric three-way regulating valve has the advantages of high regulation accuracy, stable and reliable action. Confluence type is mainly used to mix two fluids into a third fluid; Split flow type is mainly used to divide one fluid into two fluids. This product can replace two single or double seat regulating valves that are mutually switchable, and is used for regulating and controlling media such as liquids, gases, and steam.

Equipped with 361L actuator, combined with PSL actuator, split flow
