Frequently Asked Questions

Q: How do I choose between O-ring and Bellows sealing?

A: O-ring sealing is cost-effective and perfect for standard high vacuum and low-to-medium temperatures. Bellows sealing offers superior airtightness and is recommended for ultra-high vacuum, corrosive gases, or bakeable environments.

Q: What is the benefit of the "Normally Closed" pneumatic drive?

A: In the event of a power or air failure, the valve automatically closes. This prevents backflow and protects the system, which is critical when handling toxic or expensive media.

Q: Are these valves compatible with standard laboratory equipment?

A: Yes, the use of standard ISO-KF and ISO-K flanges ensures they are compatible with the majority of global laboratory and industrial vacuum equipment.

Conclusion: The High Vacuum Pneumatic Flapper Valve (Aluminum Alloy Series) is Suitable for small and medium-sized high vacuum system users, laboratories, and semiconductor manufacturers. The core advantage is its lightweight aviation aluminum design, dual-sensing precision, and versatile sealing options for high-performance vacuum isolation.
