The STAG excess / low pressure valve is used to protect containers and silos from either too high or too low pressure conditions.
If a container is exposed to excess pressure, the weight in the excess-pressure part will be pushed upwards, air will be released, and the pressure will fall. The outgoing air is led to a required location by means of a closed pipeline. This im-portant in applications where dust-contaminated exhaust air must not just be released into the environment.
If the pressure inside a container is too low, the weight in the low-pressure part will be pushed upwards, air from the sur-rounding area will flow into the container and the pressure will rise.

- Set excess pressure: +25 to +100 mbar
- Set low pressure: -15 to -100 mbar
- Temperatures up to 200 °C due to various sealing materials
- Construction materials: steel or stainless steel
We are happy to carry out the necessary revision of replaced machine components. Send us your aggregate to Maienfeld and we will inspect and revise it. Experienced mechanics and plant and apparatus engineers inspect the unit.
Each year, around 100 service assignments are carried out by STAG. From small inspections up to several-weeks of a total plant revision, our customers have Projektmanager, audit managers and audit teams at their disposal. The life-cycle-oriented service backup serves as the basis. This includes t
