Embodiments relate generally to systems and methods for monitoring and indicating the sealing of a pneumatic valve. A method may comprise detecting a position of a first magnet, wherein the first magnet is fixed to a housing cover of the pneumatic valve; comparing the detected position of the first magnet with a predetermined optimum position of the first magnet, wherein the optimum position is the position of the first magnet when there is a sufficient seal between the housing cover and a housing base of the pneumatic valve; when the detected position of the first magnet is not within a threshold of the optimum position of the first magnet, indicating an insufficient seal between the housing cover and the housing base; and when the detected position of the first magnet is within a threshold of the optimum position of the first magnet, continuing normal operation of the pneumatic valve.
