ABSTRACT:
An improved through conduit gate valve having a double expanding gate assembly with floating seats. The gate assembly carries at its edges flat guide strips which are slightly thicker than the collapsed thickness of the gate. These strips engage the seals to keep them from blinding or back wedging the gate assembly during movement between its opened and closed positions. Elastic suspension elements mount the strips to the gate assembly for proper wedging action by expansion against the seals but insures return into the collapsed position during the mentioned movement.
