The 400 Series regulators are for use with transportable D(17) and The 500 Series regulators are for use with transportable D(34A),
D(34) (17 and 34 liter) non-refillable cylinders using a CGA 600 D(58), D(76) and D(103) (34, 58, 76 and 103 liter) non-refillable
valve. These single stage, piston style regulators are designed for cylinders. These single stage, piston style regulators are designed
non-corrosive service. The control valve permits constant gas flow for non-corrosive gas service and have proven to be satisfactory
and easy on/off capability. Each regulator comes with a cylinder for use with low level corrosive gases (less than 100 ppm)*.
The control valve permits constant gas flow and easy on/off

■ Preset Flow Ratings ■ 1-1/2" x 700 psig gauge * Low level corrosive gases slowly react with the “wetted” brass parts
of the 500 Series regulators. In order to minimize loss of calibration
accuracy, the regulator must be removed from the cylinder after each
