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 and adopt a normally-closed (NC) design. 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.
