Abstract

A diaphragm-controlled differential-pressure valve has a valve housing (1) which is constructed in one piece with the lower part (5) of a diaphragm capsule (6). The associated cover (9) carries a spring housing (20) accommodating the set-point spring (18). This produces a valve having a very small overall height.
