Assignee:

Torrent Trading Ltd. - Tortola

International Classification:

F16K037/00

US Classification:

137553, 116277

Abstract:

The present invention relates to a visual valve indicator comprised of a handle assembly with peripheral sidewalls attached to a linear moving valve stem for opening and closing of the valve and a grommet stratified into one or more color bands attached to and surrounding the base of the valve stem. A breakaway portion of the grommet allows the handle assembly to close if the grommet is frozen, by breaking away from the grommet. A sawtooth-edged inner radius of the grommet allows the grommet to slide one direction when pushed down by the handle assembly, if the valve is worn.
