AirTAC 2J Series: Stainless Steel Angle Seat Valve
The AirTAC 2J Series is a high-performance, externally piloted angle seat valve designed for demanding industrial applications. Known for its robust construction and exceptional flow rates, the 2J series is an ideal alternative to standard solenoid valves when dealing with high temperatures, high-viscosity fluids, or contaminated media.
The "angle" design allows the seat to be lifted further out of the flow path, resulting in a nearly straight-through flow with minimal pressure drop. It is widely used in industries such as food and beverage, textile dyeing, pharmacy, and water treatment.
Key Product Features
-
High Flow Capacity: The Y-pattern body design provides a significantly higher flow coefficient ($Cv$) compared to traditional globe or solenoid valves.
-
Superior Media Compatibility: Available in 304 or 316L stainless steel, making it resistant to corrosive fluids and steam.
-
High Temperature & Pressure: Equipped with high-grade PTFE seals, the 2J series can handle steam and aggressive media up to 180°C.
-
Anti-Water Hammer Design: When media is fed under the seat, the valve closes against the flow to prevent water hammer shocks in liquid lines.
-
Long Service Life: Features a self-adjusting stem seal and a robust actuator that can withstand millions of cycles even in harsh environments.
-
Visual Position Indicator: Standard with an integrated mechanical indicator on top of the actuator to show whether the valve is open or closed.
