Abstract

This application discloses a sealing seat for a ball valve 10. Within a housing 12 is an apertured ball 29 which is rotatable between positions for permitting or precluding flow. The seats include a retainer 30 formed of soft metal having a projection 36 positioned to engage the ball 20 when fluid pressure acts thereon and to give structural integrity to an annular sealing member 42 formed of expanded graphite particles. This annular sealing member 42 also provides lubricity to the retainer 30 in the form of graphite particles transferred to the retainer 30 upon rotation of the ball 20 to minimize galling of the ball 20. In a modification, Fig. 5, (not shown), the projection 36 is provided with an annular groove to help retain the sealing member 42 which has metal screen wires embedded therein. <IMAGE>
