Air Release and Air Vent Valves automatically remove trapped air and gases from a piping system and, in larger models, let air back in when the system is drained. Clearing this air keeps water flowing efficiently, prevents air locks, and protects the system from pressure surges and water hammer.

Fluids: Water, Wastewater, Air

Industrial Applications: Water Treatment, HVAC, Irrigation, Fire Fighting, Pipelines

Connection Methods: Flanged, Threaded

Highlights: Automatic Air Removal, Prevents Air Locks, Improves Flow Efficiency

Considerations: Must Be Installed at System High Points, Can Foul in Dirty Water
