PRECESS vacuum valve solutions set standard in the most demanding vacuum process. A key to this is our continuous investment in R&D and our close cooperation with customers.
The VATLOCK technology which provides reliable sealing without any friction at the gate seal. A key feature of the VATLOCK is that it is locked in closing position, eliminating any risk of vacuum loss due to pneumatic failure.
The locking procedure begins as soon as the spring stop reaches the wall of the housing. The cage presses the balls out of their detents. The gate seal is pressed smoothly onto the seat. The arrangement of the balls ensures that, when there is a difference in pressure, there is an increase in the sealing force in both directions.
I-MONOVAT
With I-MONOVAT technology, the locking and sealing operation is a single linear movement, enabled by a three-dimensional gate and seat. This elastomer-sealed sealing system for vacuum gate valves distinguishes itself by its special particle- and shock-free operation over a very long-life cycle.
