ZAZQ(X) Electric three-way merging/diverging regulating valveDetailed product description：

The ZAZQ (X) electric three-way regulating valve has two types: merging and diverging. It consists of a DKZ electric actuator and three-way merging or diverging regulation. It is powered by a power source and receives a unified standard signal of 0-10mA DC or 4-20mA Dc to drive the valve opening corresponding to this operation signal. The function of a merging valve is to separate a fluid into two streams. Diverting and merging valves can only be selected accordingly, but when DN ≤ 80, merging valves can be used in diversion situations. Can replace two single or double seat regulating valves, saving investment and occupying less space. The ZAZQ (X) electric three-way merging and diverging regulating valve is commonly used for regulating two types of media in heat exchangers, as well as simple ratio adjustment.
