Abstract
A relief valve includes a first chamber with an inlet that includes an inlet valve seat and an outlet. A second chamber is spaced apart from the first chamber. A chamber wall is positioned between the first chamber and the second chamber. A closure member is movably positioned within the first chamber and is configured to be closable on the inlet valve seat. A first magnet is coupled to the closure member. The first magnet is movably positioned within the second chamber and is configured to generate a first magnetic field of a first polarity. A second magnet is positioned within the second chamber and is configured to generate a second magnetic field of a second polarity. The first magnetic field and the second magnet field interact to bias the closure member to rest on the inlet valve seat with a set force.
