A.R.I. USA Air Release Valves at Siewert Equipment & F.R. Mahony
Reliable Air Valves for Water, Wastewater & Industrial Pipelines
Siewert Equipment and F.R. Mahony are proud to distribute A.R.I. USA (a division of Aquesta) air release valves throughout New York and New England. Known for high-performance designs that protect pipelines and optimize flow, A.R.I. offers a complete range of automatic air release, vacuum break, and combination air valves for water, wastewater, and industrial applications.
Whether you’re installing a new force main or upgrading critical air control in existing infrastructure, A.R.I. valves ensure efficient system operation, prevent vacuum collapse, and reduce water hammer risks.
What Are Air Release Valves?
Air release valves are critical components in pressurized pipelines that automatically release trapped air pockets from the system. When air accumulates at high points in water or wastewater lines, it can restrict flow, increase energy usage, and cause damaging surges or cavitation.
These valves are specifically engineered to:
- Discharge accumulated air while the system is under pressure
- Admit air during draining or vacuum conditions to prevent pipe collapse
- Protect pumps and pipelines from water hammer and surge effects
- Improve efficiency by restoring full pipe capacity
There are three main types of air valves:
- Air Release Valves – Continuously expel small amounts of entrained air from a pressurized system.
- Vacuum Break Valves – Admit air rapidly into a system during draining to prevent vacuum-related damage.
- Combination Air Valves – Perform both air release and vacuum break functions in one body.
Air valves are essential for long force mains, pump stations, undulating topography, and any pipeline where flow disruption or pressure fluctuation is a concern

FAQ: A.R.I. USA Air Release Valves
Why are air release valves necessary?
- They remove trapped air that reduces flow efficiency, increases energy costs, and can cause pipeline damage or cavitation.
Can A.R.I. valves handle wastewater and sewage?
- Yes. A.R.I. manufactures air valves specifically designed for raw sewage and corrosive applications, with anti-clog and self-cleaning options.
What is the difference between an air release and combination valve?
- Air release valves discharge small pockets of air under pressure. Combination valves also allow vacuum breaking during drainage or pump failure.
Do I need multiple valves on a long force main?
- Yes. Air valves should be placed at high points, sharp elevation changes, and near pump stations. Proper spacing maximizes protection.
Can I get A.R.I. valves in stainless steel?
- Yes. Many models are available in 316SS, epoxy-coated ductile iron, or corrosion-resistant polymers, depending on the application.
How do I prevent surge with air valves?
- A.R.I. offers slow-closing and surge-arresting air valves to mitigate water hammer during rapid filling or draining.
Do these valves require maintenance?
- Minimal. A.R.I. valves are low maintenance, but occasional flushing is recommended—especially in wastewater applications.
Are these valves NSF certified?
- Yes. Potable water models meet NSF/ANSI 61 and 372 requirements.
Can I retrofit an existing valve site with A.R.I.?
- Absolutely. A.R.I. offers a range of flange sizes and adapters to simplify retrofits.
Is local technical support available?
- Yes. Both Siewert Equipment (NY) and F.R. Mahony (New England) offer on-site support and service for A.R.I. valves.
