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 NPT thread and double union connection—enabling exceptional ease of installation and maintenance. For other connection standards, please contact our customer service.
These valves are 2-wire auto return and remain in a normally-closed position. They automatically close if power is lost. A manual override is also included for use during power outages. All valves have EPDM seals for reliable performance.
NOTE 1: This auto-return ball valve requires a min. power-on duration of 60 seconds (≥60s) . This step is mandatory on first commissioning or after prolonged power cut to ensure reliable auto-reset performance.
NOTE 2: Although it is a 2-wire auto-return valve, the AC 110V-220V version has an additional orange grounding wire, making 3 wires in total.
