Abstract

1373815 Valves BRYAN DONKIN CO Ltd 14 April 1972 [28 April 1971] 11917/71 Heading F2V A pressure regulator comprises a valve member and seat cartridge 20 located in a bore inclined to the inlet 12/outlet 14 passage through the valve, the valve member being cylindrical and moving under outlet pressure acting on a diaphragm 46 to control ports 32 in a sleeve 26 of the cartridge. A knife edge 36 seats positively in the valve closed position on a valve seat insert 38. The position of the valve member is indicated by a rod 76 and scale.
