Stainless Steel Million Cycle Gate Valves (Pneumatic)

Stainless Steel Million Cycle Gate Valves (Pneumatic) for High-Duty Vacuum Automation

ThinFilmMaterials supplies ultra-reliable Stainless Steel Million Cycle Gate Valves (Pneumatic) designed for long-life operation in high-vacuum and clean process systems. Engineered for automated, high-frequency cycling, these gate valves are rated for over one million open/close cycles, making them ideal for production environments where durability and minimal downtime are essential.

Each Stainless Steel Million Cycle Gate Valve (Pneumatic) is constructed using 304L or 316L stainless steel and incorporates a robust actuator system, precision-guided gate, and metal or elastomer sealing options. The high-cycle design ensures consistent sealing performance even under rapid cycling conditions in harsh vacuum or gas delivery applications.

Key Features:

• Cycle rating: Over 1,000,000 actuations

• Pneumatic actuation: Air-open/air-close with control ports

• Valve body: 304L or 316L stainless steel

• Sealing: All-metal or elastomer seal (depending on application)

• Vacuum rating: To 10⁻⁹ Torr (UHV-compatible configurations)

• End connections: CF, ISO-F, ASA flanges or tube weld ends

• Optional: Limit switches, position indicators, and high-temperature prep

Applications:

Stainless Steel Million Cycle Gate Valves (Pneumatic) are commonly used in:

• High-throughput semiconductor processing systems

• Load-lock and transfer chamber isolation

• Automated thin film deposition tools (PVD, CVD, ALD)

• Plasma etching and vacuum pump line switching

• Cleanroom vacuum platforms requiring high reliability

These valves deliver unmatched durability with low maintenance needs, supporting continuous operation in demanding environments. ThinFilmMaterials offers full customization based on system pressure, port size, and cycle frequency requirements.
