Abstract

1535756 Valves DYNAMIC CONTROLS Ltd 1 March 1976 [15 Nov 1975] 47169/75 Heading F2V In a fluid-actuated valve having a spring 50 adjustably biasing a closure member 47 on to its seat 45, closing movement beyond a predetermined position causing deformation of the closure surfaces is prevented by abutment of the flange 48 with a stop surface 49. The closure member 47 is mounted within the perforated head of a sleeve having the flange 48 at one end once the seat is integral with a tubular extension 44 of the stop surface.
