China Ball Valves-Electric vacuum ball valve

China Ball Valve electric vacuum ball valve product overview:

TJL indusry group is a pneumatic valve used to open or cut off air flow in a vacuum system of 1.3 × 10-7 ~ 6 × 105Pa. The electric vacuum ball valve is widely applicable to both positive and negative pressure piping systems of various gases and liquids. High vacuum electric valve in line with GMP standards.

China Ball Valve electric vacuum ball valve main features are as follows:

1, unique sealing structure design, leakage rate can reach <1 × 10-10Pa.M3 / S, changing the ball valve can not meet the high vacuum, the status of ultra-high vacuum;

2, the switching torque is small, the configuration of electric actuator is small, stable and reliable;

3, compact structure, light weight, simple shape, beautiful appearance;

4, electric vacuum valve can apply both high vacuum, but also for a certain amount of positive pressure use; due to full-ball valve guide, but also to achieve ultra-high vacuum requirements, it can also be applied to the accelerator vacuum system.
