Water glycol mix is swelling the RPTFE seat
Water glycol mix is swelling the RPTFE seat
(OP)
Hello,
I have an application where the media is 50/50 water-GLycol, using a buttefly valve, with RPTFE seat. Temp is 232F, 35 psi and the seat is showing swelling, the valve has been in operation less than a year.
I can't find a chart that would give me temp ratings for Reinforced teflon and glycol, any idea why the seat may be swelling?
Please advise, thanks
