  • Control valve and system with primary and auxiliary function control
    Patent number: 10029897
    Abstract: A method of controlling a hydraulic system having a hydraulic lift function and an auxiliary function includes disabling the hydraulic lift function and the auxiliary function by routing pump flow to tank and opening the lift function and auxiliary function to tank with a single valve; enabling the lift function by closing pump flow to the auxiliary function and routing pump flow to the lift function with the single valve; and enabling the auxiliary function by closing pump flow to the lift function and routing pump flow to the auxiliary function with the single valve.
    Type: Grant

  • Hydraulic valve with spool position sensing assembly
    Patent number: 7886767
    Abstract: A hydraulic valve includes a valve body, a valve spool that is movable relative to the valve body for controlling fluid flow through the valve body, and a spool return assembly for biasing the valve spool into a centered position relative to the valve body. The hydraulic valve further includes a position sensor assembly having a sensor portion affixed relative to the valve body and a movable portion that is movable relative to the sensor portion in response to movement of the valve spool. The sensor portion is responsive to a position of the movable portion for outputting a signal indicative of the position of the valve spool relative to the valve body. The movable portion of the position sensor assembly is biased into engagement with the spool return assembly.
