ABSTRACT:
A ball valve includes a ball member rotatable in a valve chamber and cooperating with a pair of opposed seal assemblies. Each seal assembly comprises a support ring and disc spring having a resilient seal member interposed therebetween. A normally occuring void in the valve chamber is filled through use of a pair of dead space rings. These dead space rings are formed of a rigid, low friction material that does not substantially increase the torque required to rotate the ball member. In addition, the rigid material prevents cold flow of the material into the fluid passageway.
