Hydrogen fuel cell pressure regulator - AUTO 438

The AUTO438 is an EC79 approved piston-sensed pressure regulator, designed specifically for Hydrogen fuel cell buses and trucks.

During the EC79 testing process, it has been put through over 90,000 cycles by external certification body, KIWA Nederland B.V. - equating to 10 years life time on a typical installation!

With a balanced main valve as standard, it offers stable control of outlet pressures up to 20 bar (290 psi) from a maximum 438 bar (6,350 psi) inlet pressure.

Key components

Key Components of the AUTO 438 and its materials are listed as below:

Body: Material used is Anodised Aluminium T6511 (UNS AW6082)

Main Valve Pin: Material used is ASTM A479 316/316L Stainless Steel (UNS S31600/S31603)

Valve Spring: Material used is Elgiloy® (UNS R30003)

Piston: Material used is ASTM A479 316/316L Stainless Steel (UNS S31600/S31603)

O-Rings: Material used is FKM/FPM 90

Loading Spring: ASTM A479 316/316L Stainless Steel (UNS S31600/S31603)

Filter: Filter is made up of 30 Microns

Features

EC79 approved for use on hydrogen service vehicles in the public domain.

Easy access to seat cartridge for simplified servicing.
