Water-Based Fire Fighting Systems
Hydrant Air Release Valve
An air release valve vents trapped air from a fire hydrant main. Air pockets in a charged line reduce flow and can cause damaging pressure surges when the system is pressurised — an air release valve removes that air automatically so the main fills cleanly and delivers full flow. Installed at high points in the hydrant network where air naturally collects.

Frequently Asked Questions
What problem does an air release valve solve?
Air trapped in a charged hydrant main reduces flow and can cause damaging pressure surges when the system pressurises. This vents it automatically.
Where is an air release valve installed?
At high points in the hydrant network, where air naturally collects.
Is it really necessary?
Yes. A main with air pockets will not deliver its design flow when you need it.
