ABSTRACT:
In a shut-off or diverter valve, an anti-cavitation valve located downstream of the shut-off or diverter valve member vents an outlet passageway to the atmosphere to minimize cavitation in an outflowing column of water which has suddenly been isolated from the inlet. The anti-cavitation valve may be located in the interior of the shut-off or diverter valve member. When the pressure gradient between atmospheric pressure and the pressure in the just closed outlet passageway exceeds the force exerted by a spring, the anti-cavitation valve opens an air passageway communicating between the atmosphere and the outlet passageway. Part of the air passageway may be in the interior of the push rod of the diverter valve member.
