AirTAC 2W Series: Internally Piloted Normally Closed (NC) Valve

The AirTAC 2W Series is a robust 2/2-way internally piloted diaphragm solenoid valve, widely regarded as a standard for industrial fluid control. As a Normally Closed (NC) unit, it blocks flow in its de-energized state and opens when the solenoid coil is powered.

The 2W series is engineered to handle larger flow volumes than direct-acting valves. It uses a pilot-assisted mechanism, meaning it leverages the pressure of the fluid media to lift the diaphragm. This design allows for high flow rates across large pipe sizes while keeping the solenoid coil compact and energy-efficient. It is commonly found in water treatment, automated irrigation, and large-scale pneumatic systems.

Key Product Features

• High Flow Performance: The diaphragm-style architecture allows for large orifice diameters, making it suitable for high-volume liquid and gas transport.

• Forged Brass Body: The body is constructed from high-strength brass, providing excellent durability and pressure resistance.

• Pilot-Operated Efficiency: Because the media pressure helps actuate the valve, it can control high-pressure lines (up to 1.0 MPa) with minimal electrical power.

• NBR Diaphragm (Standard): Provides a reliable, bubble-tight seal for water, air, and neutral oils.

• Modular Coil System: Compatible with the full range of AirTAC coils, allowing for easy field replacement or voltage conversion (DC24V, AC220V, etc.).

• Stable Switching: Designed with an optimized internal bleed path to ensure smooth opening and closing, reducing the risk of internal mechanical wear.
