Air Valves

An air valve is a critical component in a water pipeline system that helps release trapped air, admit air when draining, and prevent vacuum formation. This ensures smooth water flow, reduces energy loss, and protects pipelines from damage.

Aquestia offers three primary air valve types:

• Automatic Air Valves – Continuously release small air pockets from pipelines.
• Kinetic Air Valves – Expel large amounts of air during filling, and admit air when draining.
• Combination Air Valves – Provide both automatic and kinetic functions, for complete air control.

The placement of air valves depends on system-specific criteria. They are typically installed at high points, at pump stations, on long sections of a pipeline, and near control valves, which are all places where air pockets are likely to form.

Proper placement prevents blockages and pressure .

For precise planning, AriavCAD — Aquestia’s dedicated engineering software — calculates the optimal valve locations based on actual system parameters.

Air valves eliminate trapped air, and in doing so they:

• Reduce pressure surges and vacuum conditions.
• Prevent pipeline bursts and flow restrictions.
• Enhance water flow stability and system longevity.

Aquestia’s air valves are designed for:

• Municipal water distribution systems
• Wastewater treatment plants
• Irrigation and agricultural applications
• Industrial fluid transportation
  
  

Aquestia air valves are made from high-quality, corrosion-resistant materials, such as:

• Ductile iron
• Stainless steel
• Reinforced polymers

This ensures long-lasting performance in various environmental conditions.

Yes, air valves reduce pressure surges caused by trapped air, minimizing the risk of water hammer. However, for full pipeline protection, they work best when combined with surge control devices.

To ensure optimal performance, air valves should be inspected every 6-12 months for:

• Air release efficiency
• Potential leaks or blockages
• Wear and tear on internal components

Yes! Aquestia’s air valves meet industry standards and are designed for both potable water networks and wastewater applications.

A.R.I air valves are engineered for high efficiency, durability, and precise air management. Their advanced design ensures quick air discharge and vacuum prevention in a wide range of applications, from municipal systems to agriculture and industry.

A.R.I combination air valves integrate both kinetic and automatic functions to expel large air volumes during filling, and continuously release small air pockets during operation. This dual-action system improves flow efficiency and protects pipelines from surges and collapses.

Yes, A.R.I air valves are built from corrosion-resistant materials, such as reinforced polymer and stainless steel. This makes them ideal for harsh environments, including corrosive wastewater, saline irrigation, and high-pressure systems.
