  • Top-entry ball valve assembly having camming surfaces
    Patent number: 6681793
    Abstract: A top-entry ball valve assembly that includes top and bottom camming plates which are coupled to top and bottom shoulders of the ball valve member. The camming plates include a first pair of opposing camming corner-surfaces to displace the spring-biased valve seat from the perimeter of the ball valve member when it is rotated between open and closed positions. The plates further include a second pair of opposing camming corner-surfaces to fully retract the spring-biased valve seat when being serviced so that the retraction tool can be inserted to hold the seats in place with little or no damage to the forward end of the seats.
