Introduction
Our electric UPVC ball valve series has been upgraded to include three larger sizes: 1-1/4", 1-1/2", and 2". These larger valves feature a unique US standard socket end & double union connection—enabling exceptional ease of installation and maintenance with a simple solvent cement bond, unlike threaded NPT or G connections. For other connection standards, please contact our customer service.
These valves utilize a 3-wire, single-control configuration. Unlike the 2-wire auto-return model, this version does not automatically reset if power is lost; instead, it remains in its current position, providing stable operation for specific flow requirements. The 3-wire setup includes a common wire, a constant power wire, and a single control wire—simply toggle the control wire to open or close the valve. A manual override is also included for use during power outages. All valves have EPDM seals for reliable performance.
To learn how to use this product, please refer to the user manual.
