Air & vacuum valve - Inlet flange for water and neutral liquids to max. 60°C (temporarily up to 90°C)

AVK air vacuum valves are designed to discharge air during the filling or charging of the system and to admit air into the system during system drainage, valve or pump shut-off or at water column separation. We also offer a range of air release valves and combination air valves combining the functions of an air release valve and an air vacuum valve.
