Fabri-Valve Figures C33 / C133 / F33 / F133 are bi-directional soft seated, slide gate valves designed for on/off service in heavy slurries. Specially designed body liners and constant contact seats minimize seat stress ensuring exceptional service life. Seats are self gasketing and are compatible with raised or flat faced, lined or unlined flanges. Figures C/F133 have a containment bonnet attached to the bottom flange to capture any discharge during cycling.
