Fabri-Valve C67 Bi-Directional Knife Gate Valve
The Fabri-Valve Figure C67 provides bubble-tight, bi-directional shutoff with its patented perimeter seal. The seal is retained in the valve body by its trapezoidal shape. A relief has been cast into the valve body. The relief greatly reduces seal compression set; the shape of the seal eliminates leakage due to seat rollover, and seat pullout.
