To provide a closed type valve for a fire fighting equipment with an antenna section freely extended to be positioned, which allows a free piping layout without any restriction on a place where to install a sensitive section.

This valve is to supply fire-distinguishing liquid to an open head, and is provided with a valve body 2 which is placed on the side of an outlet 1b of a valve case 1 and is closed against a pressure along a direction to open a valve aperture 3, a control member 4 which restricts the movement of the valve body 2 in the direction of its opening, an antenna section 5 which is extended separately from a projected part 4a disposed outside from the valve case 1 of the control member 4, and a heat-sensitive operation part 7 which covers and constrains a tip of the antenna section 5. The heat-sensitive operation part 7 reacts to a fire heat, and when the constraints over the antenna section 5 and the control member 4 are removed, the valve aperture 3 is opened due to the valve body 2 pushed up by a pressure applied to itself.
