Performance

● The Air Release Valve is automatic in operation. They have much smaller orifices than

Vacuum Valves. They release small pockets of air that gather at the high points of a system

after it is filled and under pressure.

● The Air Release Valve has the ability to open against internal pressure because it has

a small orifice and a leverage mechanism that multiplies the force of the float.

This force must be greater than the internal pressure across the orifice in order to open

the orifice when a pocket of air needs to be vented

Handling and Storage

● Lifting the valve improperly may damage it. Do not fasten lifting devices to ports in valve. Lift the

valve with slings, chains or cables fastened around the valve body, or fastened to bolts or rods

through bolt holes in the flanges.

● If installation will be delayed, place valve indoors in secure, weather tight storage. If temporary

outside storage is unavoidable, make sure a vermin proof rain cover (water shedding tarp, etc.)

is secured around/over the valve to keep off rain and mud. Skid and set the assembly on a flat,

solid, and well drained surface for protection from ground moisture, runoff and pooled rain

water.

Application:

Heating, boilers, solar water heaters, water supply systems, equipment support, etc.
