PTFE Lined Tubular Sight Glass
MVS PTFE Lined Tubular Sight Glass features 360o viewing of the process. The pfa lined tubular sight glass can be supplied in FEP, PFA, PVDF, lined Carbon Steel or stainless steel flanges. Flange ends can be supplied to suit either ASME 150 or DIN PN10/16 piping systems.
MVS PVDF Lined Tubular sight glass construction provides 360 degree process viewing with a pressure rating of up to 10 barg. It is manufactured from heavy wall borosilicate glass tube with FEP, PFA, PVDF lined flanges for use in the most demanding applications.
The Cage Construction makes our fep lined tubular sight glass extremely strong and capable of withstanding a significant amount of mishandling. The tie rod design is unique enabling adjustment of the sight glass sealing following any maintenance activity without removing it from the pipeline.
The design is both space and cost saving whilst also helping with joint reduction in the process plant.
