Magnetically controlled pressure relief valve

A magnetically controlled actuation device configured to apply a force in a linear direction, the actuation device comprising:

• a body that defines a chamber and a chamber wall, wherein the chamber is fluidly isolated from an exterior of the chamber;
• a first magnet movably positioned within the chamber, the first magnet configured to generate a first magnetic field of a first polarity;
• a closure member movably positioned within another chamber, the closure member being configured to be closable on a valve seat of at least one of an inlet and an outlet in the another chamber;
• a stem having a first end and a second end, wherein the first magnet is coupled proximate to the second end of the stem, the first end of the stem extending away from the first magnet and through an aperture that extends through the chamber wall to the exterior of the chamber;
• a biasing mechanism positioned between the chamber wall and the closure member and around the stem;
• a second magnet positioned within the chamber and spaced apart from the first magnet, the second magnet configured to generate a second magnetic field of a second polarity that is opposite the first polarity, wherein the first magnetic field and the second magnet field interact to bias the stem with the force.
