Abstract
An indicator mechanism symbolizing an operating condition of a valve. The indicator includes a body member attached to the valve and having a window opening. A guide is positioned in the body member to be visible through the window opening. A flower is also disposed within the body member and is movable between a first position retracted from and exposing the guide in the window opening, and a second position extending over and obscuring the guide from the window opening. The flower may be moved by a pressurized fluid acting directly or indirectly on the flower or by mechanical contact with another moving component such as a valve spool.
