Air Release Valve

Air release valve manufacturers in USA 

SVR Global manufactures air release valves engineered for water distribution networks, wastewater systems, pipeline infrastructure, and industrial fluid handling applications across USA. Each valve is built to remove trapped air pockets, maintain flow efficiency, and support consistent pressure management within piping systems.

What is an Air Release Valve?

An air release valve is a mechanical equipment attached to the pipes for the purpose of releasing the air pockets that develop within the pipes during operation. As water or any fluid moves within the pipe, air bubbles separate from the water and rise up within the pipes at their highest points.

How Does an Air Release Valve Work?

• Inside the valve body, a float mechanism rises and falls based on internal fluid levels. 

• As air accumulates and the fluid level drops, the float lowers, opening a small orifice that vents the trapped air. 

• Once fluid returns to fill the chamber, the float rises again and reseals the orifice, preventing fluid loss.

Types of Air Release Valves Manufactured by SVR Global:

• Double Orifice Air Release Valve - large orifice for air/vacuum exchange plus a small orifice for continuous air release under pressure

• Double Orifice Kinetic Air Valve - high volume air exchange for rapid filling or draining, protecting pipelines from surge or vacuum damage

• Single Orifice Air Valve - continuous release of small air volumes under working pressure, typically used at pipeline high points

• Combination Air Release Valve - Integrates air/vacuum release and pressurized air venting functions into one unit, reducing the need for separate valve installations along a pipeline. 

Applications of Air Release Valve:

• Water Distribution Systems - maintaining flow efficiency across municipal transmission mains and elevated pipeline sections

• Wastewater and Sewage Systems - preventing air lock and odor buildup in collection and force main systems

• Oil & Gas Pipelines - supporting air management in long distance transmission lines

• Irrigation Systems - protecting pumps and pipeline networks from air related flow disruption

• Industrial Piping - managing air accumulation in closed loop and process piping systems

Sealing Mechanism and Float Design:

• Float and seat assembly for consistent sealing under pressure changes

• Float material: stainless steel or engineered polymer

• Resilient seat design for repeated open close cycles

• Minimizes leakage across long term operation

Corrosion Resistance and Coating:

• Protective coating (e.g., fusion bonded epoxy) for exterior surfaces

• Suited for buried, submerged, or exposed installations

• Internal components treated against pitting and oxidation

• Extended service life in high moisture or wastewater environments

Orifice Size and Flow Capacity:

• Orifice sized to pipeline diameter and air discharge volume

• Prevents air lock without disrupting system pressure

• Supports small diameter distribution lines to large transmission mains

• Sizing based on pipeline hydraulic data

Body Material:

• Ductile iron, cast iron, and stainless steel body options

• Ductile iron: standard water distribution and wastewater lines

• Stainless steel: chemical exposure or aggressive water conditions

• Cast iron: buried municipal infrastructure applications
