Abstract

A diaphragm-controlled valve having a valve housing (1), in which a diaphragm (6) is also arranged. A central pipe (9) which forms part of the flow path, passes through the diaphragm (6). The valve seat (11) is provided at one end of the central pipe (9). Its other end is sealed with respect to the valve housing (1). This produces a compact and inexpensive construction.
