Abstract
1,167,658. Valves. CRANE Ltd. 14 March, 1968, No. 12422/68. Heading F2V. A plug valve comprises a ball closure member 28 located in a frusto-conical chamber 16, which is part spherical at the smaller end, by a stem 34 and a stub shaft 32, in a blind bearing 22, and a split resilient seat 24, e.g. of synthetic rubber, formed internally to surround the ball and externally to fit the chamber 16, with a conical upper surface 56 to fit a cover 52 of corresponding shape. The seat has lugs (38), Fig. 3 (not shown), which fit into recesses in the valve body to prevent it rotating. An annular recess in the cover accommodates material displaced by expansion of the seat.
