Introduction
This UPVC 3-way motorized ball valve provides an alternative solution to our standard brass/stainless steel threaded ball valves currently available. Distinguished from NPT/G threaded connections, it adopts American standard socket end & union connection, which balances stable sealing performance with the convenience of quick disassembly and maintenance.
Equipped with a 3-wire, single-control configuration, the valve does not automatically reset upon power loss; instead, it maintains its last position to ensure stable operation for specific flow control requirements. The 3-wire design consists of a common wire, a power wire, and a single control wire—users can easily switch the valve ON or OFF by toggling the control wire. A manual override function is also provided for emergency operation during power outages. With EPDM seals ensuring reliable performance, it is the ideal choice for water treatment, HVAC, and low-pressure industrial fluid handling applications. For other connection standards, please contact our customer service.
This 3-way valve series offers L-type and T-type configurations (2 options for T-type: T1/T2). Please note the distinction when purchasing (refer to the main images for flow path type details).
NOTE: For the detailed wiring diagram and the corresponding flow directions of the 3-way valve in ON/OFF status, please refer to the main image.
