Waar nodig pakt het overdrukventiel zijn verantwoording en grijpt in. Onze overdrukbeveiliging van fabrikant Bardiani is uitstekend uitgerust voor zijn rol. Ieder onderdeel van dit component dat in contact staat met het product - of met de pneumatics - wordt uit massief RVS stafmateriaal vervaardigd. Dat zorgt voor de robuustheid van het product. Zo is zijn gevoeligheid voor thermische werking minimaal.

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.
