A contactless valve actuation system includes a conduit, which may be a tubing segment in drill string or production string. The system includes a valve including a sealing member that is movable between an open position and a closed position. The system also includes a valve actuator coupled to the valve. The valve actuator is operable to move the sealing member between the open position and the closed position to open and close the valve. The valve actuator includes a sensor and a controller configured to generate a control signal in response to the sensor detecting an actuation signal generator. The system also includes a pump that is fluidly-coupled to the conduit. The pump is operable to convey fluid containing the actuation signal generator through the conduit. |
