A diverter valve (10) includes a cup-shaped, substantially cylindrical body (12) with a plurality of ports (14, 16, 18) extending from the side of the body (12), each communicating with a hollow in the body (12). A disk shaped top (20) is held in sealing engagement with the body (12). A plug (52) is rotatably positioned within the body (12) and seals against the body (12) for closing a selected one of the plurality of ports (14, 16, 18). A portion (50) of the plug (52) extends through the top (20) to permit the plug (52) to be turned. A handle (24) is coupled to the extending portion (50) of the plug (52). The handle (24) has an adjustable stop (38) for limiting the rotation of the plug (52).

Cette vanne de dérivation (10) comporte un corps sensiblement cylindrique en forme de bol (12) pourvu de plusieurs orifices de passage (14, 16, 18) communiquant tous avec une cavité ménagée dans le corps (12). Un dessus en forme de disque (20) est assujetti hermétiquement au corps (12). Un boisseau (52), qui est positionné rotatif à l'intérieur du corps (12), vient au contact de celui-ci pour fermer un orifice de passage sélectionné (14, 16, 18). Une partie (50) de ce boisseau (52) traverse le dessus précité (20) et ce, afin que l'on puisse le faire tourner. Une poignée (24), qui est rattachée à cette partie (50) du boisseau (52), comporte une butée réglable (38) destinée à limiter la rotation du boisseau (52).
