Erdmann Corporation Fabri-Valve Bi-directional Knife Gate Valve Item # C67

The Fabri-Valve Figure C67 features a unique, patented, perimeter seal that provides bi-directional shutoff. The seal is retained in the valve body by its trapezoidal shape. A relief has been cast into the valve body behind the seal. Designed to overcome the problems experienced with existing perimeter seal designs, the relief greatly reduces seal compression set; the shape of the seal eliminates leakage due to seat rollover, eliminates seal pullout due to fluid velocity, and eliminates grooves that collect material and prevent the valve from properly closing. This unique valve design is available in stainless steel and carbon steel. Stainless steel bodied valves have white EPDM seals as standard. Carbon steel bodied valves have black EPDM seals as standard. Black Viton or white Viton, AFLAS, Hycar, Hypalon, Neoprene, HNBR, and other seal materials are available as options. All Figure C67 knife gate valves with handwheels include a provision for a locking device.
