  • Lock assembly for hydraulic fracing valve
    Patent number: 8985552
    Abstract: A lock open device for use with a valve in a hydraulic fracturing system, which maintains the valve in an open position. The lock open device includes a plate with beveled edges and spring loaded ball bearings strategically disposed to contact the edges and interfere with axial movement of the plate. The plate couples to a gate member in the valve, so that the interference between the plate and the ball bearings maintains the valve in a designated open or closed position. The angle of the bevel regulates how much force is required to urge the plate past the ball bearings to thereby open/close the valve.
    Type: Grant

  • Differential screw assembly for varying torque for valve
    Patent number: 8690121
    Abstract: An assembly for actuating a valve that is in a differential screw assembly when the valve is in a portion of its stroke that experiences high resistance. The actuating assembly is selectively changeable into a direct drive configuration when the valve is in a lower resistance portion of its stroke. A sliding sleeve moves axially within the actuating assembly and has a profile that is strategically dimensioned to change the actuating assembly configuration.
