The invention relates to a flow adjustment valve (1) comprising a valve box (2) having a flow channel (3) and a connecting piece (10), disposed at an angle to the flow channel (3). A throttle unit (6) is arranged in the flow channel (3) and comprises a throttle element (8) that can be actuated through the connecting piece (10). The flow adjustment valve also comprises two measurement points (14, 15) for detecting the pressure in the flow channel (3) at both sides of a throttle arrangement, each of which measurement points is connected to a pressure measurement connection (17) via a pressure measurement channel (26, 27). The aim of the invention is to improve the design options for a flow adjustment valve of the aforementioned type. For this purpose, at least one pressure measurement channel (26) is guided through the connecting piece (10).

La présente invention concerne une vanne de régulation de débit (1) comportant un corps de vanne (2) qui présente un canal d'écoulement (3) et une tubulure (10) placée selon un certain angle par rapport au canal d'écoulement (3). Un dispositif d'étranglement (6) placé dans le canal d'écoulement (3) présente un élément d'étranglement (8) qui peut être actionné à travers la tubulure (10). La vanne de régulation de débit comprend également deux points de mesure (14, 15) permettant de détecter la pression dans le canal d'écoulement (3) des deux côtés d'un dispositif d'étranglement, chacun de ces points étant respectivement relié à un raccord de mesure de pression (17) par un canal de mesure de pression (26, 27). L'objectif de cette invention est d'augmenter le nombre de configurations possibles d'une telle vanne de régulation de débit. A cette fin, au moins un canal de mesure de pression (26) passe à travers la tubulure (10).
