Abstract
Flexible, plastic, solids-containing liners or panels are disposed in the chamber of the valve body for contacting, interfacing engagement with the gate. Accordingly, the panels and gate substantially fully occupy the chamber, and prevent an entry of slurry solids thereinto. The panels are rubber-backed to insure that the panels are pressed, sealingly, against the flat faces of the gate, and are arranged in parallel with the chamber walls.
