Abstract
Remote travel feedback systems and related methods are disclosed. A valve position feedback system disclosed herein includes a valve, an actuator operatively coupled to the valve, a pressurized fluid supply fluidly coupled to the actuator, the fluid supply spaced apart from the valve and the actuator, and a coupler to operatively couple the actuator to the fluid supply, the coupler to adjust a feedback signal in the fluid supply based on a position of the actuator, the fluid supply to provide an output to the actuator based on the feedback signal and an input signal.

A valve position feedback system comprising:
- a valve;
- an actuator operatively coupled to the valve;
- a pressurized fluid supply fluidly coupled to the actuator, the fluid supply spaced apart from the valve and the actuator;
- and
- a coupler to operatively couple the actuator to the fluid supply, the coupler to adjust a feedback signal in the fluid supply based on a position of the actuator, the fluid supply to provide an output to the actuator based on the feedback signal and an input signal.

A system comprising:
- a fluid supply system to be fluidly coupled to an actuator, the fluid supply system to be mounted in a remote location relative to the actuator, the fluid supply system to provide an output to the actuator based on a feedback signal and an input signal;
- and
- a coupler to couple the actuator to the fluid supply system, the coupler to be directly engaged with the actuator to cause a portion of the coupler to move with the actuator, the movement of the portion of the coupler to cause a change in the feedback signal in the fluid supply system at the remote location.
A valve position feedback system comprising:
- means for adjusting fluid flow;
- means for actuating the means for adjusting fluid flow;
- means for positioning the means for actuating, the means for positioning mounted remotely from the means for actuating and the means for adjusting fluid flow;
- and
- means for adjusting a feedback signal in the means for positioning based on a position of the means for actuating, the means for positioning to adjust an output provided to the means for actuating based on the feedback signal.
