Abstract

A ventilation valve for closing a ventilation duct in a casting mold, the valve comprising a valve cylinder a valve piston slidingly received by the valve cylinder so as to be movable between an open and a closed position in a direction perpendicular with respect to said ventilation duct, said valve closing in the direction of the pressure exerted onto the surface of said piston which faces said ventilation duct, a displacement member which urges the piston into its open position when the mold is open and means actuated by closure of the mold to move the displacement member away from the piston so that the piston can be brought to its closed position without being hindered by the displacement member load.
