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.
