(54) Cylinder valve for controlling gas flow from a high pressure storage cylinder


(57) Valve body 9 screws into the top of the cylinder and fits under the standard cap in place of the usual manual valve. Flow from the cylinder through valve inlet 6 is controlled by spring-loaded valve 22 which can be opened by button 40 acting through sealing diaphragm 37 on pin 31 projecting from valve 22. Button 40 is actuated by a piston 50 driven by fluid pressure supplied through a remote control valve 60. The outlet from the valve body is fitted with a spring- biassed valve which is opened when a connector is attached to the outlet. Between this valve and the outlet is a one-way flow restrictor.
