1/8inch I.P. male connect, Up to 50psi

For use on convector radiators, baseboard radiation and radiant panels.

Designed for use where space is limited. May be installed in trouble spots previously neglected or improperly vented.

Operation

The valve is always in a closed position until the air collects in the valve shell. When sufficient air accumulates to replace the waer, the float drops and the float lever pulls downward on the self-closing valve, unseating it. As the air passes out of the vent, liquid again fills the valve shell which raises the float, causing the valve to seat once again. As fast as air accumulates, this action is repeated.

For use on systems with pressures up to 50 pounds.
No air chamber required.
Vertical mounting
size: 2 5/8inches x 1 1/2inches
Bright brass finish.

This item works with the 9AS Shortstop Automatic Shutoff valve, allowing vents to be changed without draining the system.
