AirTAC 2S Series: Stainless Steel Direct Acting Normally Closed (NC) Valve

The AirTAC 2S Series (Direct Acting) is a high-precision, 2-port, 2-position solenoid valve featuring a body forged from 304 Stainless Steel. Designed for purity and durability, this "Normally Closed" (NC) version remains shut by default and opens only when the coil is energized.

Because it is direct-acting, the electromagnetic force of the coil moves the internal plunger directly, allowing for a zero-pressure startup. This makes it an essential component for medical devices, food and beverage equipment, and laboratory automation where fluid pressure may be too low for standard piloted valves to operate.

Key Product Features

• 304 Stainless Steel Body: Provides exceptional resistance to corrosion, rust, and chemical degradation. It is highly suitable for deionized water, alkaline fluids, and neutral gases.

• Zero-Pressure Functionality: Operates reliably from 0 MPa (0 psi), making it the perfect choice for gravity-fed systems, siphoning, and vacuum applications.

• Rapid Response Time: The simplified direct-acting mechanism allows for high-frequency switching and instantaneous opening/closing.

• Superior Seal Integrity: Typically paired with VITON (FKM) or high-grade NBR seals to ensure a bubble-tight shutoff even under fluctuating temperatures.

• Compact Footprint: Small orifice sizes (ranging from 2.0mm to 5.0mm) allow for a space-saving design that fits easily into compact industrial manifolds.

• Low Power Consumption: Engineered to provide maximum magnetic pull with minimal wattage, reducing heat buildup in the media and surrounding environment.
