Overpressure

protection

Where necessary, the pressure relief valve takes responsibility and intervenes. Our overpressure protection from manufacturer Bardiani is excellently equipped for its role. Every part of this component that comes into contact with the product – or with the pneumatics – is made from solid stainless steel bar stock. This ensures the robustness of the product. Thus, its sensitivity to thermal action is minimal.

Furthermore, its flexibility is remarkably great. Because of the many valve housing combinations you can literally and figuratively go in all directions. This provides plenty of options for optimal cleaning of the valve. Do you also need a special? Let us know. You ask, we run.

Maintenance has also been considered. With our solid body version (without clamping band), the valve housing can remain in the pipework. The standard o-rings are widely available and easy to install. Is an older generation fitted? Then the stainless steel parts will also remain available. We guarantee that.
