Introduction

This series of valves are suitable for starting and breaking pipes in ultra-high vacuum equipment, made up of  manual and pneumatic valves, with stable movement,  reliable, great sealing, long service life and so on, is the first choice for ultra-high vacuum equipment.

Characteristics

• Simple structure and easy to change and maintain.

• Easy to clean up.

• Shaft seal is sealed by bellows, other parts are by viton, no lube;

• Valve bodies material is stainless steel, interior welded structure, leak rate is very lower;

≤1.2×10⁵Pa any direction

Leak rate of valves’ body and base：

1.3×10^-7Pa·L·s-1 

Cycles until first maintenance：

800,000 times

Baking Temperate of valve bodies：

 opening≤200℃; closed≤150℃

Compressed air (only supply to pneumatic valves)

0.4～0.7MPa

Mounting position：

Any position

Power supply：

AC220V 50Hz, 6W or DC 24V, 3W, (Special specification can be customized)

Speed of valve closing and opening:

 ≤1s 

Indications of valves’ position:
