Abstract

_ A safety cut-off valve comprises a closure member 21 hinged at 28 and held open by a latch 19, 20 which is supported on a pin 18 joined to a ring 16 disposed in a sealed housing 9, carrying a second pin 13 located in a groove (12), Fig. 2 (not shown), of a spindle 6 connected to a diaphragm 2 actuated by the source of pressure to be controlled, and loaded in one direction by a spring 4, and in the opposite direction by a spring 5, so that, upon an increase or decrease in the pressure to be controlled, the latch is released and the valve closes. To open the valve, the closure member shaft 28 is rotated manually by means of a squared end (27), Fig. 3 (not shown), against the action of a spring 23. The upper part of the housing 9 is closed by a removable flange 8. A manually actuated bleed valve (31), Fig. 4 (not shown), is provided for relieving pressure in the casing. The ring 16 can be supported also by a third pin 24.
