(EN) TWO-SHUTTER THREE-WAY VALVE
(FR) VANNE TROIS VOIES À DEUX VOLETS
Abrégé
(EN)
Three-way valve (1) with two shutters (5,6) positioned respectively in two of the three passageways (2, 3) of the valve comprising means (7-12) for controlling and actuating the shutters (5,6) in order to cause them to pivot from one to the other of two positions in which the passageways (2,3) are opened and closed. Single control means (7) are provided for both shutters (5,6) and there are actuating means (9-12) arranged to be controlled by the single control means (7,8) and to actuate the two shutters (5,6) with a time shift.
(FR)
Vanne trois voies (1) à deux volets (5,6) respectivement disposés dans deux des trois voies (2,3) de la vanne comprenant des moyens (7-12) de commande et d'actionnement des volets (5,6) pour les entraîner en pivotement de l'une à l'autre de deux positions d'ouverture et de fermeture des voies (2,3). Il est prévu des moyens de commande uniques (7) pour les deux volets (5,6) et des moyens d'actionnement (9-12) agencés pour être commandés par les moyens de commande uniques (7,8) et pour actionner les deux volets (5,6) avec un déphasage temporel.
