Zusammenfassung:	A diaphragm valve has a first, second, and third ports, each of which for fluid entry or exit, and an adjustable diaphragm. In one aspect, a housing of the valve has at least a portion made from a transparent material such that the diaphragm is visible during operation of the valve. In another aspect, the valve includes a plastic housing having a metallic threaded portion to receive a compatibly threaded fastener to secure a periphery of the diaphragm to the housing. In another aspect, the valve also includes a plurality of fins disposed on the housing and axially extending along a branched portion of the interior passage. L'invention concerne un robinet à membrane qui comporte des premier, second et troisième accès, chacun pour l'entrée ou la sortie de fluide, et un diaphragme réglable. Selon un aspect, on décrit un logement de robinet ayant au moins une partie en matériau transparent, de sorte que le diaphragme soit visible durant le fonctionnement du robinet. Selon un autre aspect, le robinet comprend un logement en plastique à partie métallique filetée qui reçoit une fixation compatible filetée pour la fixation d'une périphérie du diaphragme sur le logement. Selon un autre aspect encore, plusieurs ailettes se trouvent sur le logement et s'étendent en direction axiale le long d'une partie ramifiée du passage intérieur.
