Abstract

A pilot regulator provides a control pressure for a principal regulator through which a gaseous fluid flows intermittently. This arrangement is used to regulate pressure upstream or downstream in industrial gas pipeworks. A pilot regulator comprises a cylindrical body (22) with an intermediate annular section (23) and cylindrical cap (24) which are bolted together. A membrane (25) between the body and annular section senses a differential pressure between the downstream pressure (P3) and the atmospheric pressure in the chamber (28) augmented by spring (27) pressure. The membrane operates a flat element (31) against a tubular element (32) to form an exhaust valve. The pilot pressure (P1) tends to lift this valve to allow the controlled inlet pressure (P2) to communicate with the downstream pressure (P3).
