3 Way Electric Ball Valve Female Threaded

Electric 3 way ball valve is divided into L-port 3 way electric ball valve and T-port 3 way ball valve electric.The electric L-port 3 way ball valve is used to switch the flow direction of the medium, which can connect two channels perpendicular to each other.The T-port 3 way electric ball valve is used for diverting & mixing of medium and flow direction switching.

3 way electric ball valves are widely used to switch the flow direction of the medium and to divert or mix the medium in water supply,petrochemical,metallurgy,mining,textile,energy, paper,food,steel and other pipeline systems.
