摘要：
Swing valves have a passage and a sleeve. The passage has a receptacle, and the sleeve is pressure fitted into the receptacle. The sleeve is adapted to conduct flow through the valve and comprises a first end, a second end, and a valve seat. The first end of the sleeve is pressure fitted into the receptacle. The second end projects out of the receptacle. The valve seat is on the face of the second sleeve end. The second sleeve end also is adapted to couple with a sleeve cap extending over and across the second sleeve end to shut off flow through the sleeve.
