Explosion-proof Electric Three Way Ball Valve
Explosion-proof electric three-way ball valve is driven by an explosion-proof electric actuator, capable of diverting, converting and reversing flow with reliable sealing, suitable for flammable and explosive working conditions such as petrochemical industry.
Features
Three-way ball valves are used for flow diversion or confluence. They are multi-port ball valves equipped with two or four valve seats. Any port can serve as the inlet with zero leakage. Three-way valves can be designed with either L-port or T-port.
The T-port flow channel adopts four valve seats, featuring balanced force distribution and reliable sealing.
Mainly used for flow diversion, mixing, reversing, and full opening of three passages.
The L-port flow channel adopts two valve seats and is mainly used for flow path switching.
