ABSTRACT:
The gate assembly (24) of an expanding gate valve has projecting pins (74, 76, 78) which engage guide surfaces (54, 66) of guide rails (52, 64) in order to maintain the gate assembly in a collapsed condition between its open and closed positions. At the fully open and fully closed positions, the pins register with gaps (56, 58, 60, 68, 70) in the guide surfaces to permit expansion of the gate assembly against a pair of valve seats (20, 22).
