A fire-extinguishing-system valve (2) having a housing (4), having a fluid-entry chamber (26) provided in the housing (4), having a fluid-exit chamber (24) provided in the housing (4), and having a closing body (28) which can be moved back and forth between a blocking state (32) and a release state (34) and, in the blocking state (32) prevents direct fluid flow between the fluid-entry chamber (26) and the fluid-exit chamber (24) and, in the release position (34), connects the fluid-entry chamber (26) to the fluid-exit chamber (24) directly for fluid-conducting action. The fire-extinguishing-system valve (2) has at least one sensor device (18) for directly monitoring the position of the closing body (28).
