Abstract
The invention relates to a double valve with a valve housing (1), for housing two double-headed actuators (30, 31), whereby the double head actuators have differing head diameters (12, 13) and the flow of a fluid through the both actuators (30, 31) in the valve housing (1) is identical. The valve housing (1) is of one-piece design and a drive function for both actuators (30, 31) is not connected to the inner volume of the valve housing (1) with fluid flowing therein.
Claims8
A double valve comprising a valve housing (1) for receiving two serially connected double-disk actuators (30, 31), wherein the double-disk actuators have different disk diameters (12, 13) and the afflux flow by a fluid to the two actuators (30, 31) in the valve housing (1) is identical, characterised in that the valve housing (1) is of a one-piece configuration and that a drive function of the two actuators (30, 31) is not connected to the internal space of the valve housing (1), through which space the fluid flows.
