Aerosol Can Valve Disassembler. This unit is for destructive testing. It allows you to remove the valve components for visual testing & measurement. Observe for gasket swelling. Disassembles most valves with ease. Must be mounted down to a table at about waist height. This way you can use your body weight to assist the disassembly. On some very heavy steel valves you may use a soft face hammer on the handle to get it started.
