  • Block and bleed valve with a magnetic coupled switch
    Patent number: 9046190
    Abstract: A valve assembly having a body, a float assembly, a switch magnet, and a sealing surface that opens or closes a block and bleed valve in response to movement of the float assembly. The float assembly may be pivotally attached to the body at a pivot axis. The float assembly may have a first end and a second end opposite the first end, where the pivot axis is located between the first end and the second end. The float assembly may further comprise a float attached to the first end and a float magnet attached to the second end, such that raising the float causes the float magnet to lower and lowering the float causes the float magnet to rise. The switch magnet may be responsive to movement of the float magnet, and the sealing surface may be responsive to movement of the switch magnet.
