Foam Concentrate, Hydraulically Actuated Control Valve

This valve is installed downstream of the foam concentrate holding tank and is closed in its normal, set position. The valve is forced open by its master valve’s downstream pressure rise when it opens. This allows the foam concentrate valve to open even with zero upstream line pressure, ensuring fail safe supply of foam concentrate through the foam proportioner downstream of the main master valve.



  • Full stainless steel construction
  • Double-chamber, zero pressure, fail safe operation by its master valve’s water mains
  • Electric remote actuation and remote reset including local manual emergency actuation
  • Applicable for control of water & seawater, AFFF concentrate foam systems
