  • Three-way valve with flow diverter
    Patent number: 8122908
    Abstract: A three-way valve body comprises a throat defining a generally cylindrical throat cavity. At least one flow diverter is carried by the valve body and extends into the throat cavity. The flow diverter advantageously interrupts any circulatory fluid flow within the throat cavity, thereby increasing the efficiency at which fluid flows through the valve body. In one embodiment, the at least one flow diverter can comprise one or more ribs integrally formed with the valve body and disposed parallel to a central axis of the throat cavity.
