ABV has a collar that is marked with arrows indicating settings for manual and automatic operation.

Manual Operation Return to Automatic Operation

Lift collar up.
Rotate base counter
clockwise until right arrow
( ) aligns with A on the
collar.

For the ABV-NC, the valve can be opened manually by turning the collar in a counterclockwise
direction as indicated. Likewise when tted with ABV-NO, the valve can be manually closed by
turning the collar in a clockwise direction

Lift collar up.
Rotate base clockwise until
triangle ( ) aligns with A
on collar.

Push collar down.

Automatic
control settings:

Operation:

The ABV when mounted to the VMT has the unique ability of provide automatic control with or with­out stem travel limitation. When the collar is raised, the scale setting is exposed.

A

With the right triangle ( , AUTO) set to “A” on the collar’s scale, there will be a full ow rate through
the valve, i.e. the entire travel of the valve stem and 100% of the valve’s Cv. If the triangle ( ) is set
to any other position along the collar’s scale, the maximum stem travel will be reduced resulting in a
reduced ow rate and Cv value.
