Valve assembly

摘要

A valve structure has a main gas channel (5) fitted with a membrane device (6) for opening and closing it and for controlling its position via a main magnetic valve (20). An inlet (9) and outlet (10) for the main gas channel connect to a bypass gas channel (11) that can be opened and closed via a bypass magnetic valve (13). A pressure sensor (18) links to the outlet side for controlling the main magnetic valves by means of an electronic unit.
