Hydrogen Pressure Regulator - HPR

  • Designed for fuel cell applications
  • Outlet regulated pressure from 8bar to 16bar

Add to compare

The HPR Hydrogen Pressure Regulator is a mechanical double stage regulator designed for fuel cell applications. It integrates components such as inlet/outlet ports, an inlet filter with 10 microns, a pressure relief valve (PRV), and an excess flow valve (EFV). It can be customized with high and low pressure sensors, a low pressure service valve, and adjustable outlet pressure ranging from 8bar to 16bar. The regulator is certified for use in various transportation sectors and features a high-precision mechanical assembly with multiple ports and mounting points. It is available with inlet options of 700bar (Voss / Autoclave OD 3/8) and 350bar (SAEJ 1926), and the PRV can be customized for activation. The HPR is a key component in ensuring safe and efficient hydrogen pressure regulation in fuel cell systems.
