The HVA 11210-0203RS-001 Gate Valve features a stainless steel 304 body and mechanism designed for durability and high vacuum integrity. Its welded bellows shaft seal (AM-350) ensures leak-free operation without rotary seals, while the million-cycle hardened stainless steel drive shaft and pins guarantee long-term reliability in demanding environments. The valve is suitable for high-purity, vibration-sensitive processes such as semiconductor fabrication.
Equipped with versatile sealing options, the valve offers Viton® elastomer bonnet and gate seals for standard high-vacuum (HV) applications, and OFHC copper/Viton® elastomer combinations for ultra-high-vacuum (UHV) conditions. Temperature resistance ranges from 150 °C for elastomer-sealed bonnets to 200 °C for open metal-sealed bonnets, ensuring adaptability across various process requirements.
The HVA 11210-0203RS-001 includes pneumatic linear actuation and an optional overcenter or soft-closure mechanism, maintaining a closed status even during air pressure loss. Shock and vibration are minimized by a unique air cylinder design, providing smooth, reliable operation for critical systems. Its compact interior design reduces surface area and, combined with vacuum furnace brazing at 1100 °C and 1×10⁻⁶ Torr, ensures minimal body distortion and eliminates virtual leaks.
For system integration, the valve supports air service up to 80 psig, solenoid actuation at 4.0 W, and electrical connections with supplied 120 VAC 50/60 Hz or optional 24, 200, 240 VAC. The valve also accommodates position indicators up to 115 VAC or 28 VDC at 20 mA, enabling precise monitoring in complex process setups.
