High Vacuum Pneumatic Pendulum Valve for Semiconductor and Coating Systems

This high-performance High Vacuum Pneumatic Pendulum Valve is a premier vacuum isolation and transmission component specifically engineered for ultra-high vacuum (UHV) environments, compact layouts, and processes sensitive to particle contamination. Utilizing a sophisticated pendulum-style rotary opening and closing mechanism, it is designed to operate seamlessly across the full pressure spectrum from 5×10⁻⁸ Pa to 1×10⁵ Pa. Whether you are managing a high-end vacuum pump setup or a complex industrial line, this valve ensures rapid connection, isolation, and hermetic sealing between vacuum chambers and pipelines.

Core Features & Technical Advantages

• Flexible Pneumatic Actuation: Supports multiple driver configurations, including Pneumatic Normally Closed (NC), Pneumatic 3-Stage NC, and Pneumatic Double Acting. Integrated safety springs in NC models ensure the valve closes automatically during power or air failure.
• Universal Flange Compatibility: Standardized with ISO-F and JIS B flanges, making it a "plug-and-play" solution for various vacuum equipment configurations.
• Premium Material Construction: The main body is crafted from high-grade aluminum alloy (customizable materials available), offering high strength, lightweight handling, and extremely low outgassing rates for cleanroom environments.
• Customizable Modular Design: Optional heating and water-cooling modules are available to meet specific process temperature requirements. Bypass ports can also be integrated upon request.
• Wide Operational Range: Stable performance from ultra-high vacuum levels to atmospheric pressure, providing total coverage for diverse industrial cycles.
• Extended Service Life: The pendulum structure minimizes friction and wear during operation, resulting in low vibration and minimal particle generation. Its split-body design allows for rapid maintenance and easy integration into automated production lines.
