Air valves

The Importance of Air Valves

Trapped air pockets in a piping system can lead to several issues, including:

• Accelerated corrosion

• Increased energy usage and operational costs

• Inaccurate flow measurements or failures in flow metering

• Pressure loss or complete flow stoppage during main filling

• Higher risk of water hammer

These trapped air pockets can cause sudden changes in flow velocity, resulting in high-pressure surges that can be destructive to the system

Role of Air Valves

Air valves are crucial in both clean water and wastewater networks. Properly selected air valves help mitigate issues caused by transient pressures and trapped air in pipelines, which are major contributors to pipeline damage such as bursting, collapsing, and fracturing. Effective air valve selection enhances pipeline efficiency, reduces premature failures, and lowers overall lifecycle costs. Despite their importance, air valves are sometimes undervalued, leading to their neglect or closure, which undermines their intended protective and efficiency-boosting functions. Choosing the wrong type of air valve can lead to performance and efficiency problems within the system.

AVK Air Valve

AVK air valves are designed for superior performance, minimal maintenance, and long-lasting durability. Our valves feature ductile iron components coated with GSK-approved fusion-bonded epoxy for enhanced durability. Non-metal components are made from WRAS-approved polymers or stainless steel to resist corrosion. Additionally, our valves use WRAS-approved EPDM rubber seals known for their excellent compression set and ability to return to their original shape, ensuring reliable performance.
