Fuel Cell Valves

Without any sliding component, fuel cell valves incorporating a metal bellows offer low friction and low leakage. By equalizing the pressurized areas of the valve and bellows, the effects of upstream pressure fluctuations are cancelled.

Features

  • The EKK Fuel Cell Valve regulates the pressure of hydrogen gas supplied from tank to fuel cells.
     
  • It is highly stable and responsive due to a structure that enables the controlled downstream pressure and solenoid thrust to be in balance when controlled.
     
  • Solenoid thrust characteristics are optimally designed to reduce the effects of downstream gas usage (flow rate) fluctuations.
