Resistant to pressure surges Air release and admittance functions Efficient against water hammer in pipelines All types of air valves for water and wastewater networks For above- and underground installations
Air release outlet in NOMINAL SIZE (large opening cross-section according to the flange size).
Flange according to EN 1092 (DN 50 also available with 2" threaded connection).
Efficient vacuum protection through high ventilation performance.
Optimal ventilation without early closure owing to very high air outlet speeds when filling the pipes or reservoir.
Effective protection against water hammers with high air release speeds thanks to the 2-stage ventilation system.
