The self-packing feature precludesany possibility of valves of this type leaking at the stuffing boxes. By a special device placedin the stuffing boxes, the packingis automatically kept tight andwill last for years without re-newal. The device is very simple,consisting only of a vulcanizedwasher located at the top of stuff-ing box and kept in position byspring compression, which fullycompensates for the wear onwasher. These valves open andclose by turning the lever handleone-half turn. To open, turn tothe left; to close, turn to the quickTopening and closingfeature will no doubt be appre-ciated by users who have operatedThe lever handle can be operated.
