Introduction

This series of valves are made up of manual, pneumatic and electromagnetic angle valves, with reasonable design on structure, small shock vibration, small volume, durability, great sealing, long service life and so on, is the first choice for vacuum equipment.

Characteristics

• Simple structure and easy to change and maintain.

• Easy to clean up.

• Electromagnetic valves are designed in an energy saving way and the size is small.

Differential pressure before open valve plates：

DN 200~250 (pneumatic)：≤3×10⁴Pa;

others：≤1.0×10⁵Pa any direction

Leak rate of valves’ body and base：

1.3×10^-7Pa·L·s-1 

Cycles until first maintenance：

200,000 times

Baking Temperate of valve bodies：

 ≤150℃

Compressed air (only supply to pneumatic valves)

-0.4～0.7MPa

Mounting position：

Manual: any position

Pneumatic: any position (DN≤160); sealing surface faces to vacuum (DN>160)

Electromagnetic: any position (bellow sealed); sealing surface faces to vacuum (rubber gasket sealed)

Power supply：

-Pneumatic: AC220V 50Hz, 6Wor DC 24V, 3W, (Special specification can be customized)

-Electromagnetic: AC 220V 50Hz

Speed of valve closing and opening:

-Pneumatic:  DN16~DN50 ≤1s   DN63~DN250 ≤3s 

-Electromagnetic: opening≤0.1s; closed≤1s ( rubber gasket sealed), closed≤0.5s( bellow sealed)

Indications of valves’ position:

-Manual: with indication of start and stop 

-Pneumatic: with indication of start and stop (magnetic switch)

-Electromagnetic: with indication of start
