Abstract: The present invention relates to a valve for a spray system for spraying a washing liquid comprising a valve body, enclosing a hydraulic cavity which is configured to be fluidically connected to a hydraulic conduit of the spray system and is intended to receive the washing liquid, a mobile element which is configured to be moved in the hydraulic cavity between an open position, in which it lets the washing liquid pass into the hydraulic conduit, and a closed position, in which it blocks the passage of the washing liquid into the hydraulic conduit, characterized in that the valve also comprises at least one opening provided in the wall, said opening being closed by an elastic membrane which is configured to be deformed if the washing liquid freezes in the hydraulic cavity.
