Abstract

The invention relates to a valve (1) comprising a main valve (2), a pilot valve (3), a housing (4), an inlet (5) and an outlet (8). Opening and closing of the main valve (2) is controlled by the pilot valve (3). A pilot valve seat (10) is arranged in a diaphragm (6). A pilot chamber (11) is arranged in the housing (4) separated from the inlet (5) and the outlet (8) by the diaphragm (6). Task of the invention is to provide a valve with a lower cost. According to the invention a support member (17) supports the diaphragm (6), wherein the support member (17) is guided in the housing, and wherein a radial gap (26) is arranged between the radially outer end of the diaphragm (6) and the housing (4) in a radial direction perpendicular to the opening direction of the pilot valve (3). Thereby, a cheaper, less resistant material for the diaphragm can be used.
