FIELD: mechanical engineering, regulation of pressure of liquid media, specifically in water supply systems. SUBSTANCE: pressure regulator has case, inlet and outlet spaces, control space, sensitive element, spring, gate, seat, rod, setting space. Walls of hole of seat in outlet space are perforated which makes it possible to put gate on side of inlet space and to provide it and rod with functions of additional sensitive element with negative feedback by inlet pressure and to manufacture main sensitive element in the form of sleeve mounted in cylindrical part of case and made leak-proof by membrane and corrugation and spring-loaded relative to cover that forms threaded pair together with case.
