  • Valve positioner system
    Patent number: 6745084
    Abstract: A valve positioner system that includes one or more unique control methods and devices, including several routines to facilitate the continuous maintenance, calibration and adjustment requirements of the valve. The positioner system may utilize pressure and position feedback signals to monitor the valve. The positioner system may utilize an external controller for various diagnostic and other routines. The positioner system can provide automatic positioning and can operate in a manual operating mode or an automatic operating mode. The positioner system can diagnose the valve while the valve process is running or during a maintenance operation. The positioner system can provide nonlinear control of the valve position. The positioner system can self-tune and self-characterize the valve to assure uniform position control. The positioner system can provide valve control through pressure feedback when a position feedback fails or other diagnosed problems.
