Abstract (en)

[origin: WO2018109077A1] The invention relates to a fire extinguishing system valve (1), in particular a wet alarm valve, dry alarm valve or spray water valve, having a housing (2, 3) that has a fluid inlet chamber (8), a fluid outlet chamber (9) and a closing body (4a) that can be moved back and forth between a blocked state and a release state, wherein the fluid inlet chamber (8) and the fluid outlet chamber (9) communicate directly with each other in a fluid-conducting manner in the release state, and the closing body (4a) prevents direct communication between the fluid inlet chamber (8) and the fluid outlet chamber (9) in the blocked state, characterised by a bypass line (10) integrated in the housing, which bypass line is connected in a fluid-conducting manner to the fluid inlet chamber (8) and to the fluid outlet chamber (9).
