AirTAC 2KS Series: Stainless Steel Direct Acting Normally Open (NO) Valve

The AirTAC 2KS Series (Direct Acting) is a 2-port, 2-position solenoid valve constructed from high-grade 304 Stainless Steel. Designed for precision and durability, this "Normally Open" (NO) version stays open when de-energized, allowing fluid to pass through. When the coil is powered, the internal plunger is driven down to seal the orifice.

Because it is direct-acting, it does not require any internal pressure differential to function, making it the premier choice for stainless steel requirements in vacuum systems, low-pressure chemical dispensing, and food-grade applications where a zero-pressure startup is mandatory.

Key Product Features

• 304 Stainless Steel Body: Offers superior resistance to corrosion and oxidation, making it suitable for deionized water, medical environments, and mildly aggressive chemicals.

• Zero-Pressure Startup: Operates reliably from 0 MPa (0 psi), allowing it to control fluids in gravity-fed or siphoning systems where piloted valves would fail.

• Normally Open (NO) Security: Ideal for cooling systems or safety bypasses where flow must be maintained during a power failure to protect expensive machinery.

• High-Speed Actuation: The direct-acting plunger mechanism provides near-instantaneous response times, essential for precision dosing and sampling.

• Compact and Robust: Despite its stainless steel construction, the 2KS series maintains a small footprint for easy integration into high-density manifolds.

• Precision Seals: Standard with high-performance seals (often Viton) to handle elevated temperatures and ensure a bubble-tight shutoff when energized.
