VLF In-line Balanced Pressure Proportioner
The “VLF” In-Line Balanced Pressure (ILBP) proportioner is a foam proportioning device which is 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.
Construction features: ; • Available in 3” (DN80), 4” (DN100), 6” (DN150), 8” (DN200) ; • Brass construction or Nickel Aluminium Bronze construction for superior corrosion protection ; • Suitable for horizontal or vertical installation ; • Direction of flow indicator on body ; • For use with fresh or salt water
