Abstract
Various devices and techniques related to magnetically-actuated valves are generally described. In some examples, valves may include a valve body with a cavity. Valves may include a stem at least partially disposed in the cavity. Valves may include a valve member coupled to the stem. Valves may include a ferromagnetic actuation member disposed in the cavity. The ferromagnetic actuation member may be operatively coupled to the stem such that movement of the ferromagnetic actuation member actuates movement of the valve member between an open position and the closed position. Valves may include an actuator exterior to the valve body. The actuator may include a first magnetic pole section and a second magnetic pole section. A magnetic flux may flow from the first magnetic pole section through the ferromagnetic actuation member to the second magnetic pole section in a magnetic flux path through the interior portion of the valves.
