  • Axial drag valve with internal hub actuator
    Patent number: 8312893
    Abstract: In accordance with the present invention, there is provided an axial drag control valve which includes an internal disk stack trim and an internal actuator. The fluid inlet and outlet of the valve are disclosed along a common axis, which is further shared with both the plug and the actuator. The plug and actuator move along this particular axis to control the fluid flow rate, pressure, or temperature of the system. The valve actuator may be powered by an operating fluid such as air supplied from an external source. A special, two-part packing with a lantern ring and leak-off port provides protection and safety for the actuator.
