  • Continuous magnetic motion position indicator
    Patent number: 9671040
    Abstract: A continuous magnetic motion position indicator detects the position of a clapper valve. The clapper valve comprises a valve body and, disposed within the valve body, a clapper and a valve stem. The continuous magnetic motion position indicator comprises: (a) a magnetic joint assembly comprising a first set of magnets disposed inside the valve body and a second set of magnets located outside the valve body that operatively interface with the first set of magnets, and (b) a remote position transmitter and/or a local visual indicator. In operation, the magnetic joint assembly transmits rotary movement of the clapper from the valve stem to the remote position transmitter and/or local visual indicator, without the presence of a dynamic seal interface.
