Abstract

1435411 Valves DANFOSS AS 5 Feb 1974 [6 Feb 1973] 05276/74 Heading F2V A valve for an air duct comprises a closure member 13 pivotably mounted on a lever 12 together with a balancing weight 10 and a biasing weight 14, 15 which closure member is moved against the biasing weight by bellows fixed under a plate 7 also attached to the lever. The weights 14, 15 are movable along the arms 12 of the lever and are of different values to facilitate a coarse and fine adjustment. The weights may be locked in position and the arms are graduated to indicate the position of the weights.
