Cylinder Pressure Regulator

Dual Stage in stainless steel electropolished with purge system for corrosive gases

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, while discharging the cylinder) or when the working pressure is very low.

To identify the correct order code for your HP103

Start with "HP103-", then add the appropriate number options from columns A, B, & C  in the table below followed by the gas to be used.

HP103-2-4-3-Argon specifies a HP103 model with 300 bar inlet pressure, 1-12 bar outlet pressure ranges & diaphragm metering valve, for use with Argon gas.

Inlet Pressure Ranges Outlet Pressure ranges Options for the outlet
1 = 200 bar 1 = 0.1 - 1 bar 0 = 1/4“ NPT f
2 = 300 bar 2 = 0.1 - 3 bar 1 = compression fitting 6 mm
  3 = 1 - 6 bar 2 = membrane shut-off valve
  4 = 1 - 12 bar 3 = diaphragm metering valve
