Description Technical Specifications Downloads Vendor

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.
  • In-line vent leakage sense line to sense for H2 leakages, and makes set point anti-tamper proof.
  • Balanced main valve design for improved control across the pressure range.

Benefits

Product features is correlated with the advantages of products as listed below:

  • EC79/2009 approved: Permits use on hydrogen service for vehicles in the public domain.
  • Easy access to seat cartridge: Simplified servicing through the base of the regulator.
  • In line leakage sense line: Easy to connect pipework to sense for H2 leakage, and makes set point anti-tamper proof.
  • Balanced main valve: Improved control across the pressure range.

Mounting configuration options

Two mounting options are provided for the end user based on the user requirement:

  • Bonnet mounting: Mounting panel is secured between the body and bonnet with a panel mounting nut.
  • Head-work mounting: Mounting panel is secured between the body and head-work

Application areas

  • Hydrogen fuel cell trucks
  • Hydrogen fuel cell buses

Pressure Tech Ltd

Pressure Tech is a UK manufacturer and was established in 2000 by owner Steve Yorke-Robinson. We are now renowned world over for the manufacture of high-quality pressure regulators. In 2017 we started work on expanding our product range into the Hydrogen Fuel Cell market with the development of our lightweight LW351 pressure regulator for UAV H2FC drones. We have since added an EC79 approved regulator for Hydrogen buses and trucks, a TPED approved cylinder valve for Hydrogen gas cylinders and a full range of pressure regulators for material handling applications, passenger vehicles and refuelling stations.
