4" Sightglasses and Flanges
The BF4 series of sightglasses and flanges are made to suit 4" TTMA flanges/piping.
Flanges provides the ability to make a removeable connection between two points.They have a chamfered bore to clear the disc, fitted beside a butterfly valve.
Sightglass flanges bolt directly behind an outlet adaptor and provide the ability to view product in piping to ensure if a compartment/tanker has product present or if it has been drained.
The standard drilling for sightglasses is TTMA, so the unit will fit behind an API adaptor as well as Liquip butterfly valve. (Max pressure - 1,000kPa, Max temp - 70oC).
