For exact dimensions, please request certified dimensional drawings from the factory 2
3 Theory of Operation The valve design is based on a double eccentric geometry of the disc rotating center, utilizing a floating radius machined seal ring, in conjunction with an inclined cone seating surface of body. This design makes the disc cam back and away from body seat, eliminating wear between the seat and seal ring. It also compensates for deviations of the geometry caused by temperature or tolerance changes. (Fig. 1) The disc seal of valve deflects from its regularly circular shape to an elliptic form when it reaches the closed position. This matches the inclined cone of body seat geometry, creating the sealing between disc seal and body seat. Dimension changes due to temperature fluctuations cause the seal ring to adjust its seating position within the inclined cone geometry, thus maintaining a positive seal as usual. Due to the unique conical surface of the valve, there is a preferred and non-preferred flow direction. The preferred flow direction would be with the shaft upstream and the direction is marked on the body with a directional arrow. The shaft side is referred to as the high pressure side of the valve. Preferred direction of flow 3
