Electric Three Way Control Valve includes Electric Three Way Mixing Control Valve (GZDLQ) and Electric Three Way Diverting Control Valve (GZDLX). Mixing Control Valve is mainly used to mix the medium from 2 different ports and let it flow out through the third port. Diverting Control Valve is to separate the medium from one port and let it diverted flowing out through the other 2 ports. When the Valve size is small and pressure differential is small, Mixing Control Valve can also be used as Diverting Control Valve. But if the valve size is big and pressure dro is big, both can not be replaced each other.
