Three Way Ball Valve

Three-Way Ball Valve

Three way ball valve

Three way ball valve are suitable for switching, mixing and diverting corrosive or non-corrosive liquids, gases and powder media at temperatures from -46℃ to +200℃. During the opening and closing process, the flow path is smooth reducing the pressure loss. 

Three way ball valve is effortless to operate and easy to maintain. Five types of flow to meet different process requirements, can be manual, pneumatic, electric control.

Structure Features and usage

Three way ball valve is made up of one worm gear, manual operating stem, and double three-way ball valves. 

The feature is that the two ball valves are set symmetrically, with one common stem, reliably and efficiently solving synchronous switching for two symmetrical ball valves. Such valve is easy to operate, and works reliably.
