ZHSF(H) type electric three-way merging (diverging) regulating valveDetailed product description：

1、 Overview

The ZHSF (H) electric three-way merging (splitting) regulating valve has two types: merging and splitting, which are operated by DKZ electric actuator and three-way merging or three-way splitting
Composition of regulating valve. Powered by a power source, it 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 merge two fluids into a third fluid, while a diverging valve divides one 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. Three way regulating valves are commonly used for regulating two types of media in heat exchangers, as well as for simple ratio adjustment.
