Reliable and economical general-purpose components designed for high vacuum (HV) and ultra-high vacuum (UHV) applications, ensuring cleanliness and corrosion resistance.
When in the open position, the edge-welded bellows and valve seat move out of the gas path, achieving high conductance. Key features include:
- Fluorocarbon O-ring seat seals for enhanced leak protection.
- Bellows-sealed shafts and bonnet seals, with an option for copper seals to withstand higher temperature bakeouts and improve ultimate vacuum performance.
- Easy maintenance, allowing for normal repairs without the need to remove the valve body from the system.
