HP 103 is a dual stage cylinder regulator with integrated inert gas purge system.
The regulator is equipped as a standard with gas specific cylinder connection according DIN 477 or other common national standards, relief valve and inert gas purge system on the high pressure side.
Dual stage regulators will be preferred when the working pressure should be absolutely stable (even if the inlet pressure drops, dis- charging of cylinder) or when the working pressure is very low.
For corrosive gases and gas mixtures with high requirements on safety, tightness and compatibility of material.
