Abstract: A rotary valve has a valve housing with a wall defining a flow passageway, a closure member journalled within the valve housing and mounted for movement between a first position for permitting flow of fluid within the flow passageway and a second position for ceasing flow of fluid within the flow passageway, and a flexible seating ring disposed at least partially within the flow passageway in a position for sealing engagement with the closure member in second position. The flexible seating ring has a flow-through section sized to fit within the flow passageway with a clearance fit, and a flanged seating section extending outwardly from the flow-through section and positioned for sealing contact with the closure member to seal the valve. A seating ring support member is positioned to support the seating ring in a manner to permit the seating ring to move axially and radially within the flow passageway to provide improved tolerance to dimensional variation in manufacture.
