Ventileinrichtung

摘要

The invention relates to a valve assembly for controlling the differential pressure and comprising a valve casing (1), a control device (7, 70), a first, a second and a third connections (2, 3, 4), a first sealing seat (11, 110), a second sealing seat (12, 120) and a valve body (5, 50), of which the cooperation with the first sealing seat (11, 110) controls a first link between the first (2) and second connections (3), and of which the cooperation with the second sealing seat (12, 120) controls the link between the second (3) and third connections (4). In order for such a setting to be optimized, it is suggested by the invention that the sealing seats (11, 12, 110, 120) be axially opposite each other and should have the same active diameter, and that the valve body (5, 50) be located between the sealing seats (11, 12, 110, 120).
