Abstract

A kit of parts for a differential-pressure control valve comprises a valve housing (4), a first diaphragm capsule (2) and a second diaphragm capsule (3). By suitable configuration of the fixing elements (28, 38, 56, 62) two different arrangements of valve can be achieved using largely the same components.
