FL FLOW BFSG FLOATING BALL

Show Sections

The BFSG combines all the benefits of the CTSG tubular sight Glass with its 360 degree process viewing with an integral hollow PTFE ball and soft fluoropolymer seat. The design is both space and cost saving, typically used to prevent liquids travelling down vacuum lines with visual indication.

The BFSG has a heavy wall borosilicate glass viewing section and PFA lined carbon steel flanges. The glass is supported with a robust stainless steel tie rod ‘cage’. The hollow PTFE ball sits on a lower integral castellated trap allowing gas to freely flow past and up through the sight glass, if liquid enters the sight glass chamber the ball floats on the liquid level travelling up to the soft seat mounted within the upper flange preventing liquid travelling further.   The BFSG tie rods can be adjusted without removing from the pipeline all wetted parts are PTFE, PFA and Borosilicate Glass.

A combined heavy duty borosilicate sight glass with integral hollow ball check valve.  For use in sampling systems and in preventing up stream contamination of vacuum lines or instrumentation.
