Description

Suitable: 
With a preset vacuum level this valve breathes the atmospheric air and prevents the vacuum level from exceeding beyond the desired vacuum value. It is used to adjust a vacuum system with the same operating vacuum. The setting is done using a fine thread of the valve and the mechanical opening due to the spring load. 

Materials: 
Nickel-plated brass 

Information: 
The vacuum can also be controlled when there is a permanent leakage in the vacuum system. This can be achieved by one of our needle valves. 

Information: 
These valves are generally delivered with coils and plugs!
