ABSTRACT:
A gate valve having a cylindrical angle-transported disc gate pivotally moveable into a channel closing position in which it is in sealing engagement with a packing ring disposed in a radial packing groove in a body defining the channel. The outer diameter of the packing ring is smaller than the diameter of the packing groove so that when the gate is pivoted into a channel closing position in sealing engagement with the packing ring, the ring is biased into tight sealing engagement with the gate.
