Seat assembly for valve

A valve, comprising:

• a body assembly having a valve chamber and an inlet passage and an outlet passage in communication with the valve chamber, the body assembly further having at least one sealant injection port;
• a valve member positioned in the valve chamber and movable between an open position and a closed position, the valve member having a flow passage formed therethrough for providing fluid communication between the inlet passage and the outlet passage of the valve body when the valve member is in the open position;
• and
• a seat assembly extending about the inlet passage and engaging the valve member, the seat assembly comprising:
• an annular seat carrier having an inner side, an outer side, an inward facing side, and an outward facing side, the seat carrier having an annular sealant groove formed along the inner side of the seat carrier, the seat carrier having at least one sealant injection port extending through the seat carrier from the outer side of the seat carrier and intersecting the sealant groove, the sealant injection port of the seal carrier being in fluid communication with the sealant injection port of the valve body for injecting a sealant into the sealant groove;
• and
• a sealant distribution member extending along the sealant groove of the seat carrier to cooperate with the seat carrier to define an annular sealant flow path along the inner side of the seat carrier, the sealant distribution member having a plurality of openings formed there through to provide a plurality of fluid flow passageways from the sealant groove for injecting the sealant between the seat carrier and the valve member.
