Stainless Steel Bellows Sealed with Elastomer Bonnet Inline Valves (Manual)
Stainless Steel Bellows Sealed with Elastomer Bonnet Inline Valves (Manual)
ThinFilmMaterials offers cost-effective and durable Stainless Steel Bellows Sealed with Elastomer Bonnet Inline Valves (Manual) for use in high vacuum and rough vacuum systems. These manually operated valves combine the reliability of welded bellows sealing with an elastomer bonnet to provide a leak-tight, flexible solution for vacuum isolation where full UHV performance is not required.
The design incorporates a welded stainless steel bellows for stem sealing, while the elastomer bonnet provides smooth operation and serviceability. The inline valve body allows direct flow-through connection, making it ideal for compact system layouts.
