Abstract: The expansible tube-type regulator has long been known as a unique regulator, to distinguish it from conventional regulators. Webster defines unique as being without like or equal, and conventional as commonplace. This regulator is still considered unique however, by an increasing number of gas companies, it has become known as a conventional regulator. The operating member is an expansible tube. This tube is slipped over a cylindrical metal core having a series of longitudinal slots at each end, with a separating barrier between. Action of the expansible tube is determined by control of the differential pressure across it. The Flexflo valve operation resembles a diaphragm motor valve with the expansible tube acting as both diaphragm and inner valve. The tube is made from a formulated synthetic elastromer especially compounded to assure a high degree of tear and abrasion resistance, flexibility and strength.
