Kieselmann aerate and air relief
Applying the Kieselmann anti vacuum Valve for hygienic industries
An anti vacuum valve can be used to prevent impermissible pressure shortfalls (≤1 bar absolute pressure) in tanks, a silo and storage containers, which can result in damage. The valve opens to the atmosphere and the pressure in the tank is brought to the atmospheric pressure by the inflowing air. With pressure equality the Kieselmann Anti Vacuum Valve closes by spring tension.
The hygienic stainless steel design makes it perfect for use in industries as Food, beverage and dairy industrie. They are available with different connections like clamp, threaded version and DIN 11851 welding connections. Seals are available in silicone, Perbunan and standard EPDM.
