4. 00 ratings soft sealed constructions only The double offset eccentric operating principles of both seal off set the seal ring centerline is offset from the shaft centerline see Figure 1 and shaft offset the shaft centerline is offset from the valve centerline see Figure 1 allows the disc to get off the seal quickly due to the camming rotation with respect to the valve seal centerlines This results in minimal sliding friction producing con tact between the disc and the seal ring with complete separation after only a few degrees of rotation The overall characteristics of the Masoneilan 39003 Series Valve are listed below Long seal life Offset eccentric operation gets the disc off the seal quickly minimizing sliding contact and friction resulting in reduced seal wear and lower breakaway and seating torque requirements Fast dynamic operation Offset eccentric operation elim inates disc to seal friction throughout the operating range resulting in fast response to input signals Also the disc tends to move in the direction of flow assisting the valve and actuator to maximize the allowable operating pressures Excellent flow characteristics the offset eccentric disc design provides an approximate equal percentage flow characteristic through its full travel of 90 rotation yielding a Cv ratio of 100 1 Extra heavy shafts with keyed ends for actuator mounting precise and accurate positioning wit
