Model VLF In-Line Balanced Pressure Proportioner

Foam systems require various system components — such as the Model VLF In-Line Balanced Pressure (ILBP) Proportioner — for effectiveness and quality in flammable liquid protection.

ILBP proportioners are foam proportioning devices which are used to balance the higher foam concentrate pressure to the lower system water pressure on Pilot Pressure Regulating Systems or Foam Pump Proportioning Systems. The ILBP is particularly useful in providing accurate proportioning at multiple riser locations that are situated remotely from the central foam concentrate storage tank.
