INTRODUCING THE AUTO438...
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.

PLEASE CONTACT THE PRESSURE TECH OFFICE FOR PRICING.

APPLICATIONS:
• Hydrogen Fuel Cell Trucks
• Hydrogen Fuel Cell Buses

FEATURES:
• EC79 approved for use on hydrogen service vehicles in the public domain
• Easy access to seat cartridge for simplified servicing
• In-line vent port for simplified assembly
• Balanced main valve design for improved control across the pressure range
