The original design and development of this regulator was conceived by the cavagna group(reca). Compact quick-on type 634 is a non-adjustable single-stage low-pressure regulator with an inlet connection designed to fit automatic cylinder valves. Its compact and ergonomic shape makes this regulator perfectly handy and easy to use. To fit the regulator to the gas cylinder, first position the regulator on top of the automatic valve and then click it simply by exerting some downwards pressure. Gas opening and closing is done by a 1/4 turn of the regulator handle. The compact quick-on can be connected to or removed from the automatic valve only when the regulator handle is in the closed position(horizontal position). All the compact quick-on models are equipped with a thermal safety device(fuse) which shuts off the gas flow in case of fire in the vicinity of the regulator /gas cylinder.
