Hawle air valves are essential components in pipeline networks. They ensure the controlled release of air and allow air to enter the pipeline when required.

Responsibility of the water Utility

According to SVGW guidelines, air valves must be inspected annually. Particular attention should be paid to checking components for damage, as well as verifying the mobility and proper operation of the float. The valve seats and closing plugs must be inspected to ensure unobstructed flow.
In addition, valve seats and O-rings should be checked for wear, ageing and damage.

The unrestricted functionality of the air valve system must be ensured at all times to prevent damage and operational disruptions within the pipeline network.
