4-Way Ball Valve Motorized
Description
TECHNICAL DATA SHEET
Motorized 4-Way Ball Valve
Multiport Flow Control · Electric Actuated
1. PRODUCT DESCRIPTION
The Motorized 4-Way Ball Valve is a multiport quarter-turn rotary valve designed for directional flow control, flow diversion, and media mixing in complex piping systems. Featuring a four-port body with a specially configured ball core (X / LL port design), this valve enables simultaneous switching of flow paths between two media with a single 90° rotation.
The electric actuator provides automated, remote-controlled operation, making this valve ideal for power station cooling water systems, petrochemical switching applications, HVAC, and industrial process control where reliable flow redirection is essential. The motorized 4-way ball valve replaces multiple two-way valves, simplifying piping layouts, reducing installation space, and lowering overall system costs.
