A valve position indicator includes a first shell form body and a second shell form body. The first body has an exterior surface marked with a first colour indicia and a second colour indicia. A rotatable valve actuator knob is non-rotatably secured to the first body. The second body overlies the first body and has viewing windows. Rotation of the second body is limited relative to the first body to a closed rotational position in which the first colour indicia is visible through the viewing windows and an open rotational position in which the second colour indicia is visible through the viewing windows. The second body is locked in the open rotational position until a preset locking tension is overcome.
Cette invention concerne un indicateur de position de robinet composé d'un premier corps en forme de coquille et d'un second corps en forme de coquille. Le premier comporte une surface extérieure portant un premier et un second codes couleur. Le volant de manoeuvre tournant du robinet est solidaire du premier corps surmonté du second corps qui comporte des fenêtres d'observation. La rotation du second corps par rapport au premier est limitée entre une position fermée où un code couleur est visible par les fenêtres d'observation et entre une position ouverte où le second code couleur est visible par lesdites fenêtres. Le second corps est verrouillé en position fermée jusqu'à ce qu'une tension préréglée de verrouillage soit dépassée.
