SVFI – STERILE VISUAL FLOW INDICATOR

The in-line sight glass offers the highest quality and precision demanded by the modern food, chemical and pharmaceutical industry. Using the best and certified materials this fitting has been designed to a high specification. The bore of the Borosilicate glass element is precision sized to match precisely the bore of the flange ends/connecting pipe work. The resulting smooth transition obtained by this and by adopting the EHEDG guidelines regarding o-ring seal profile is designed to give a hygienic CIP cleanable product. The unit has four observation windows resulting in maximum visibility combined with adequate strength to withstand design pressures and temperatures. The product is fully certified and conforms to EC directives.

The o-ring seals are both FDA food grade and USP Class VI quality, fully certified. The metal body is permanently part marked with material heat number, size, surface finish and the CE mark. Other markings can be applied as requested. The basic unit is ASME-BPE SFF6 on the internal bore, however higher finishes can be supplied, as can more exotic grades of materials.
