ABSTRACT:
A multiple plate valve is provided which is designed to continue to function to close off a conduit even after portions of the valve have worn. The valve includes a body portion in the form of a pair of outer cover members each having an aperture therein, at least a pair of closure members, such as plates, operatively retained between said outer cover members and adapted to be moved between open and closed positions and to cooperate with each other to close off the apertures in the outer cover members, and means for repositioning the closure members with respect to each other and the apertures, as the closure members wear out, so that the closure members will continue to cooperate with each other to close off the apertures.
Such a valve is particularly useful where it is employed in a conduit used for delivering abrasives or caustic chemicals which tend to wear out the closure members of the valve.
