Abstract
Methods and apparatus for estimating a condition of a seal of a rotary valve are disclosed. An example method includes determining a seal wearing cycle of a flow control member of a rotary valve. The seal wearing cycle includes movement of the flow control member between a first position in contact with a seal and a second position. The example method further includes determining a torque of an actuator operating the flow control member for the seal wearing cycle and estimating a condition of the seal based on the torque.
