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