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 double union connection for exceptional ease of installation and maintenance. The pipe sockets are made to a US standard and use a simple solvent cement bond, unlike threaded NPT or G connections. For other connection standards, please contact our customer service.
These valves feature a 5-wire configuration for enhanced control and monitoring, yet remain in a normally-closed (NC) position. They utilize two wires for the power supply and three dedicated wires for signal feedback only. Unlike the 2-wire model, this configuration provides two-way position signaling (Open/Closed) to your control system for real-time status monitoring. For safety, they automatically close (auto-return) if power is lost. A manual override is also included for essential operation during power outages. All valves utilize EPDM seals for reliable, long-term performance.
