The 2W series signal feedback solenoid valve is an upgraded intelligent fluid control component based on the classic 2W direct-acting platform, integrating a high-precision position sensor or limit switch on the valve stem assembly. This industrial-grade valve is capable of transmitting real-time electrical signals (normally open/normally closed passive contacts) to central control networks, PLCs, or DCS units, allowing automation systems to instantly verify whether the valve is currently in the fully open or fully closed position. Utilizing a robust semi-direct acting lifting diaphragm structure, it operates seamlessly from zero pressure differential up to its maximum rated capacity, delivering highly reliable media isolation alongside precise remote monitoring capabilities for modern automated water treatment, chemical piping, and intelligent factory infrastructure.

Feature

Real-Time Position Monitoring: Equipped with an integrated signal feedback module that outputs precise opening and closing status signals, preventing systemic operational errors caused by undetected valve execution failures.

Zero Pressure Differential Start: The semi-direct acting (lift-assisted) configuration allows the valve to open and close stably even at 10 bar system pressure, making it ideal for low-pressure gravity-fed and vacuum lines.

Premium Materials & Long Lifespan: Crafted with precision forged brass or heavy-gauge SS304 stainless steel bodies, paired with high-performance diaphragms (NBR, EPDM, or FKM) to ensure excellent chemical compatibility and wear resistance.

Highly Responsive Execution: Features an optimized electromagnetic coil system that delivers rapid response times, high motive power, and stable continuous operation under standard industrial cycles.
