Abstract
A sliding gate valve and more specifically one in which bilateral symmetry is preserved in both the stationary plate and the slide gate. More specifically, the slide gate is provided with a metallic frame which retains a monolithic refractory into which errosion resistant refractory inserts or preformed members are cast. Means are desirably provided to remove the spent refractory for remanufacture thereby reclaiming the casting. Both the stationary plate and the slide gate casting have spring pad back up reinforcements. The stationary plate desirably has means for securing a well nozzle to it.
