6A Air Vent
INSTALLATION AND MAINTENANCE INSTRUCTIONS
The 6A Air Vent has both a float and a thermostatic
bellows for use where air, condensate and steam may
be present (as in one pipe steam heating systems.)
The 6A will discharge air, while preventing the escape
of either condensate or steam. An outlet check valve
prevents the re-entry of air.
Limiting Operating Conditions
Max. Operating Pressure (PMO) 15 psig (1 barg)
I n s t a l l a t i o n
The air vent should be positioned with the inlet at the bottom at the
highest point in the piping system or equipment where air collects.
The valve will be closed when either condensate or steam enters
the body. The discharge can be hot and wet, and the 6Ashould be
positioned accordingly.
