Abstract

1401754 Valves FIP VORMATURA INIEZIONE POLIMERI SpA 1 May 1974 [11 June 1973] 19105/74 Heading F2V In a rotary ball valve a cylindrical valve body housing an apertured ball 4 and annular seals 6 is connected to tubular flanged connecting members 7, 8 by threaded bushes 11, 12. Each seal is substantially triangular in cross-section and is urged towards the ball by an 0-ring 14. A reduced diameter flanged portion 13 of each connecting member 7, 8 allows the latter to partially enter the body 1 to take up clearance on wear of the seals. The seals are replaced by unscrewing the bushes 11, 12 and moving the body laterally from between the members 7, 8.
