FVFI – FULL VIEW FLOW INDICATOR

Advanced Couplings Ltd can also offer a range of Full View Flow Indicators to a high specification as demanded by the industry to meet the ever increasing need for product cleanliness and integrity. Targeting the Food, Chemical and Pharmaceutical Industry where cleanability is of the essence, these items are of the highest quality.

 

The stainless steel flange ends are designed to suit standard clamp type coupling joints as given in the various published standards. The flange ends support the glass element on the outside diameter and also provide the housing for the face seal. The face seal is designed on the EHEDG principle utilising a precise deformed o-ring, this gives the unit its remarkable cleanability characteristics. The stainless steel flanges are offered in 316L stainless steel as standard although Hastalloy C22 and AL6XN can supplied upon request.

 

The seals themselves are to FDA food grade and USP Class VI specifications, offered in a variety of elastomer types. Seals are supplied individually packed with all relevant details such as grade, size, material, cure-date etc. Packaged seals have a shelf life of 7 years minimum. Specialist seals can be provided for conditions outside the scope of the standard seal.

 

The unit is assembled with stainless steel spacer studs & nuts. Studs are precision sized to ensure the correct seal compression and are fully polished as are the dome assembly nuts. The glass element of Borosilicate Glass Type 3.3 is sized to a precision bore to match the ferrule/tube size, also with polished ends making it a high quality, functional item.
