​XLH-25: Vacuum On/Off, Precision Control! Dedicated Vacuum Valves Empower High-Vacuum Environments​

In high-tech sectors such as semiconductor, photovoltaics, and vacuum coating, there are extreme requirements for establishing, maintaining, and switching vacuum environments. The XLH-25 vacuum valve is specifically designed for vacuum systems. Utilizing special materials and sealing technology, it ensures highly reliable on/off control of flow paths under vacuum conditions, serving as a key fundamental component for building high-vacuum (HV) and ultra-high-vacuum (UHV) systems.​​Core Product Advantages​​​​High-Vacuum Sealing Performance​​Employs metal seals (e.g., oxygen-free copper) or special fluoroelastomer seals, offering extremely low leak rates (typically <1×10⁻¹⁰ Pa·m³/s), meeting the requirements of high-vacuum (HV) and even ultra-high-vacuum (UHV) applications.​​Low Outgassing Materials​​Key components like the valve body and stem are made from low-outgassing materials such as stainless steel, and undergo precision polishing or passivation treatments to minimize vacuum level interference caused by material outgassing.​​Fast-Actuation Structure​​Features optimized port and actuation design for quick opening and closing, enabling rapid vacuum establishment or isolation, thereby improving equipment cycle time and efficiency.​​Multiple Actuation Methods​​Offers manual, pneumatic, and electric actuation options (specific type depends on model suffix), adaptable to automated control needs.​​Standard Flange Connections​​Utilizes standard vacuum flange interfaces like CF (ConFlat) or KF (ISO), facilitating system integration and ensuring connection sealing and interchangeability.​​Typical Application Scenarios​​​​Semiconductor Equipment:​​ Pumping down and isolating process chambers for etching, PVD, CVD, etc.​​Vacuum Coating Equipment:​​ Controlling the connection between the coating chamber and the pumping system.​​Research & Experimental setups:​​ On/Off control for vacuum lines in particle accelerators, surface analyzers, etc.​​Solar Cell Manufacturing:​​ Controlling the vacuum environment in equipment such as PECVD.​​Technical Parameters (Typical)​​​​Port Size/Type:​​ DN25 ISO-KF or similar standard vacuum flange (25 may indicate nominal diameter)​​Leak Rate:​​ <1×10⁻¹⁰ Pa·m³/s​​Operating Pressure Range:​​ Atmosphere to High Vacuum (e.g., 10⁵ Pa to 10⁻⁶ Pa or higher)​​Body Material:​​ 304/316 Stainless Steel​​Seal Material:​​ Fluoroelastomer (FKM) / Metal Seal (Oxygen-Free Copper)​​Summary​​The XLH-25 vacuum valve acts as the ​​”Sealing Guardian”​​ of vacuum systems. Its core value lies in providing a reliable, tight, and controllable passage switch for high-cleanliness, demanding vacuum environments, forming the foundation for ensuring vacuum process quality and equipment performance.​​Choosing the XLH-25 means equipping your vacuum system with a reliable, stringent “valve gate,” ensuring the purity and stability of the vacuum environment!​​
