Air Valve & Air/Vacuum Valve

Compound Lever Air Release Valve

The Compound Lever Air Release Valve is used for higher capacity applications where a larger valve and double lever are needed to regulate air release. The standard Buna-N seat is suitable for cold and hot water up to 180° F. Air Release Valves, sometimes referred to as "small orifice valves," are often fitted at the highest point on a pipeline to continually release unwanted air during system operation to protect against unwanted surges and maintain system efficiency.

Air Release Valve -Wastewater

Dual Body Combination Air Valve

Single Body Combination Air Valve

The Dual Body Combination Air Valve is a two-valve assembly consisting of an air & vacuum valve and an air release valve. The combination allows the valve to exhaust large amounts of air at start-up, to release small pockets of air while the system is running, and to prevent critical vacuum conditions during draining. The Kinetic feature prevents the valve from blowing shut before all the air is vented.

A high performance combination air valve that efficiently vents air during pipeline filling, rapidly admits air during pipeline draining, and continually releases air pockets while the system is operational. Its simple design employs only two moving parts and its corrosion resistant stainless steel construction provides long term reliable operation.


Always ​American Iron and Steel Compliant

Air/Vacuum Valves, often referred to as "large orifice valves", are used to allow large volumes of air to be exhausted from or admitted into a water pipeline as it is being filled or drained. When draining the pipeline, the float drops, allowing air to enter, preventing loss of pressure, possible pipeline collapse and damaging water column separation.

American Iron and Steel compliant version available. 

​The Wastewater Air Valve exhausts air and sewage gas from pressurized sewage systems or force mains. The valve’s elongated body minimizes aspiration and helps keep solids and debris from affecting operation. Air Release Valves, sometimes referred to as "small orifice valves," are often fitted at the highest point on a pipeline to continually release unwanted air during system operation to protect against unwanted surges and maintain system efficiency.
