Product Description
                             Ultra-high Vacuum Gate Valves
 Vacuum Gate Valves with Kf/ CF/ Lf Flanges

This series of valves are made up of manual, pneumatic and electromagnetic gate straight valves. The design of this series' structure is reasonable, and the appearance is excellent. Besides, they have many advantages, such as stability, small size, durability, great sealing, long service life and so on. As a result, they can apply to the ultra-high vacuum equipment. 

1. Adopt stainless steel bellows and viton o- ring sealing, no lube. 
2. The inner of valves' body is welded by stainless steel and the leak rate is low. 
3. Valve bodies design in rib structure, with small sizes, light quality and excellent appearance. 
4. Adopt double-guide-rail structure, smooth movement; Monolithic construction inside the valve and well-distributed holding power. 

Application scope: 
1× 10-7PA~1.2× 105PA
Differential pressure before open valve plates: 
≤ 3× 103PA Any direction
Leak rate of valves' body and base: 
< 1.3× 10-7PA@L@s-1
