ABSTRACT:
A flow switch valve including a housing main body comprising a plurality of valve casings stacked contiguously and each having a fluid flow channel and a valve seat member, a valve member passing slidably through said valve casings and having valve bodies corresponding respectively to the valve heat members of the valve casings, a diaphragm disposed to any of the valve casings and supporting the valve member, and a signal generation device for detecting the position of the valve member in the housing main body and generating a detection signal. The valve member moves slidably depending on the change of the fluid pressure in the chamber partitioned by a diaphragm, by which valves for the fluid flow channels in the plurality of valve casings are opened or closed interlocking therewith and, at the same time, a detection signal for the position of the valve member is generated.
