ZDL (Q/X) electronic three-way confluence/shunt control valve is mainly used to divide an inlet fluid into two outlet fluids or two inlet fluids to synthesize one outlet fluid. Three-way is divided into (ZDLQ) confluence control valve and (ZDLX) shunt control valve. Valve size, when the pressure difference is small, the confluence valve can also be used as a diversion valve, but when the valve size is large and the pressure difference is high, do not use the diversion valve.
