Zusammenfassung
(EN)

The present invention relates to a water spray valve set for a nozzle pipe system of a fire-extinguishing installation, having a water spray valve which has a fluid inlet for connection to a water supply, a fluid outlet for connection to the nozzle pipe system, and a closing body arranged between fluid inlet and fluid outlet, wherein the closing body is movable back and forth between a shut-off position and an opened-up position, wherein, in the shut-off position, the fluid inlet and fluid outlet are separated from one another and, in an opened-up position, said fluid inlet and fluid outlet are fluidically connected to one another, having a control line which is connected to a control pressure supply, and having at least one first control valve for controlling the control pressure in the control line, wherein the control line is operatively connected to the closing body such that the closing body is held in the shut-off position, or is in an opened-up position, in a manner dependent on an actuation of the control valve. According to the invention, a relief line is provided which is connected to the control valve, wherein the control valve is designed to, when activated, relieve the control line of pressure via the relief line, such that the closing body is moved into the opened-up position, and to shut off the fluid connection between the control pressure supply and the closing body.
