When discussing air valves in sewage, wastewater, and effluent water applications, it's crucial to understand their role and the advantages offered by manufacturers like ARI. Here's a breakdown:

Role of Air Valves in Wastewater Systems:

Air Release:
Wastewater systems generate gases that can accumulate in pipelines, hindering flow and causing corrosion. Air valves release these trapped gases.
Vacuum Prevention:
When pipelines drain, a vacuum can form, potentially collapsing the pipes. Air valves allow air to enter, preventing this.
Surge Protection:
Air valves help mitigate pressure surges that can occur during pump starts/stops or changes in flow, protecting the pipeline from damage.

ARI Air Valve Advantages:

ARI specializes in air valves designed for challenging liquids like wastewater, offering several key advantages:

Design for Solids:
ARI air valves are engineered to handle liquids containing solid particles, common in wastewater.
Air Gap Technology:
A key feature is their "air gap" design, which separates the liquid from the sealing mechanism. This prevents fouling and ensures reliable operation, even with dirty liquids.
Reliability and Durability:
ARI emphasizes high-quality materials and construction, leading to durable and reliable valves.
Comprehensive Product Range:
They offer a wide range of air valves tailored to specific wastewater applications, including combination air valves, air release valves, and vacuum breakers.
Technical Support and Sizing:
They provide technical support and sizing tools to ensure proper valve selection for optimal system performance.
Focus on preventing sewage fouling:

ARI by Aquestia is selling its products online by www.irrigationglobal.com. has developed a unique range of sewage air valves which incorporates a mechanism that ensures a constant air gap to ensure no contact between the sewage and the sealing mechanism. This has solved one of the major problems with air valves on sewage, ie. Fouling up the orifice resulting in sewage leaking to atmosphere.
