ABSTRACT:
A straight-way valve assembly is provided with regulating elements in the form of discs, of which one is rotatably-mounted and includes flow ports, which correspond to flow ports of the other static discs, which static discs are arranged on opposite faces of the rotatable disc to form a mechanical, fluid tight seal, whereby the face of the rotatable disc directed away from the supply line includes one or several recesses that are in fluid communication with valve vent means when the valve is in its closed position; the recesses extending radially outwards across the surfaces of the rotatable disc.
