Variable orifice wide range proportioner

The variable orifice wide range proportioner ensures accurate foam concentrate proportioning across a broad range of flow rates and pressures. Its innovative design eliminates the need for multiple in-line balanced pressure proportioners (ILBPs), simplifying system layout and reducing cost.

Key Features:

  • Precise proportioning across a wide flow and pressure range
  • Eliminates need for multiple ILBPs in the system
  • Ideal for systems with varying flow demands
  • Certificate: UL Listed / FM Approved
  • Standard: NFPA 11, UL 162, EN 13565, GB 20031
  • Connection: Wafer, installed between flanges (ANSI Class 150, EN 1092 PN16)
  • Temperature Range:7°C to 49°C
  • Working Pressure: 30 ~ 175 psi or up to 250 psi
  • Surface Finish: Rough brass or bronze
