Electric Three-Way Flange Ball Valve (Type LQ)

The Electric Three-Way Flange Ball Valve combines LQ electric actuator with three-way ball valve, functioning as a rotary-type shut-off and regulating valve. Features include positive sealing, compact structure, lightweight design and easy maintenance. Powered by 220V single-phase AC, it operates through control system signals via reversible gear reducer for pipeline switching.

Double-seated version enables flow direction switching or connecting two perpendicular channels. Quadruple-seated version allows three-way flow distribution, selective channel closure, and flexible confluence/divert control.

Applications: Water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, steel pipeline systems.
