Abstract

1298677 Pressure regulating valves I V PRESSURE CONTROLLERS Ltd 1 May 1970 [10 July 1969] 34890/69 Heading F2V Outlet pressure acts on piston 23 via passage 26 to move it against the adjustable spring- loading 27 and thus allow the closure member 14 to follow the movement of the piston-rod 22 under the action of its spring-loading and so move relative to its seat 15 to regulate outlet pressure. The end of the rod 22 is shaped to co-operate with a seat 17 on the closure member 14 and if when the closure member 14 is closed outlet pressure rises the rod 22 will move away from its seat 17 to vent the outlet via passage 18. Passage 29 allows outlet pressure to act on the lower end of the closure member 14 so that it is substantially pressure balanced. Piston 23 may be replaced by a diaphragm and the loading may be a gas-loaded dome.
