How to choose a plug valve that is compatible with different vacuum systems? Dual dimensional interpretation of characteristics and applications
Date: 2025-06-19Read: 9
Vacuum plug valve is a device used to cut off or connect air flow in high vacuum and ultra-high vacuum systems, widely used in various scenarios that require high cleanliness air path control. Its characteristics and application areas are as follows:
Main characteristics of vacuum plug valve
Excellent sealing performance: The vacuum plug valve uses high-performance sealing rings and special materials to ensure extremely low leakage rates for a long time under ultra-high vacuum conditions. The leakage rate is usually expressed in Pa · L/s or mbar · L/s units, and the leakage rate of imported products is usually much lower than that of similar domestic products.
Quick opening and closing: The electric drive method can achieve rapid opening and closing of valves, shorten the vacuum pumping time of the vacuum system, and improve work efficiency. Some products can even achieve millisecond level opening and closing speeds, meeting certain time demanding application scenarios.
• Stable and reliable: After rigorous testing and inspection, the vacuum plug valve performs excellently in terms of working performance, and can maintain good sealing and opening and closing performance under long-term and high-intensity working conditions.
• Diverse specifications: Vacuum plug valves from different manufacturers and models provide a rich selection of sizes and specifications to meet the needs of different application scenarios.
Corrosion resistance and wear resistance: For different working conditions, materials with strong corrosion resistance or wear resistance can be selected to extend the service life of the valve.
• Convenient control: Many vacuum plug valves are equipped with convenient control interfaces, supporting multiple methods such as manual, remote, and PLC control, making it easy for users to operate and manage.
