Mechanical Hydraulic guard valve

For glove boxes operating mainly in a gaseous atmosphere and purified atmosphere, the use of a hydraulic guard has interesting technical aspects. Its characteristics are remarkable, making it possible to combine a very low opening pressure with a high flow rate.

Hydraulic guards offer many advantages, such as:

Rapid evacuation of excess gases in an enclosure.
No fluid or liquid body is used: 100% compatible with clean rooms, semiconductors and all electronic sectors.
Maintaining the enclosure at the pre-set working pressure.
Increased comfort of handling with gloves.
Eliminates the need for a vacuum pump in the pressure regulation process.
Safety equipment allows users to mechanically control an accidental rise in pressure.
