Air Release Valve

Air Release Valve

Category

Air release valves automatically remove trapped air from pipelines to support stable flow and reliable system.


Air trapped inside a pressurized pipeline can gradually reduce the usable flow area, increase pumping demand and create unstable pressure conditions. Air release valves help remove this trapped air automatically while keeping the process fluid contained.

SVR Global supplies these solutions as an Air Release Valve Manufacturer in USA, with configurations designed for continuous air venting, high-volume air discharge and controlled air admission during different stages of pipeline operation.

What is an Air Release Valve?

An air release valve is an automatic float-operated valve normally installed at pipeline high points, pump discharge locations and other areas where air naturally collects.

As air enters the valve chamber, the liquid level falls and the float moves downward, opening the vent orifice. The trapped air is discharged until liquid rises again and lifts the float back into the closed position. This cycle takes place automatically while the system remains pressurized.

Types of Air Release Valves

Combination Air Release Valve

Double Orifice Air Release Valve

Double Orifice Kinetic Air Valve

Single Orifice Air Valve

Air Release Valve Features

• Automatic float-operated air discharge

• Continuous release of trapped air during normal pipeline operation

• Large-orifice options for rapid air movement during filling or draining

• Resilient sealing for dependable closure after air is discharged

• Corrosion-resistant internal float and trim components

• Flanged and threaded configurations for different pipeline layouts
