KNIFE GATE VALVE
Fabri-Valve Figures C37 and F37 are some of the most popular knife gate valve configurations. Figure C37 knife gate valves through 24”, feature a heavy duty, rugged one-piece cast body, chest and flanges (except 5”, which is fabricated – F37). Sizes larger than 24” are fabricated from heavy plate.
The Figure C/F37 is available in all stainless steel (designated “S”) or with alloy steel wetted parts and carbon steel external parts (designated “R”). In sizes 1.5” through 24”, the “S” and the “R” share the same solid cast body. Sizes larger than 24” feature fabricated bodies configured to the service conditions.
The Figure C/F37 is available with the widest range of seats in the industry including: integral metal, replaceable hardfaced metal, rubber “D” ring, replaceable rubber, polyurethane, UHMW-P, and PTFE. Standard body materials include 304, 316, and 317L stainless steel. Special alloys such as 254 SMO® are also available. Special flange drillings are also available.
