PTFE / Teflon body seals on ball valves
PTFE / Teflon body seals on ball valves
(OP)
Dear all,
I am looking for some advice please.
What I am wanting to know is...are there any ball valve manufacturers who use PTFE body and stem seals on ANSI 600 and above?
Services to include:
Glycol, Natural gas, Hydrocarbons, Methanol
Ambient -46 to +200C teperature range
Thanks for any help,
Stiffler

RE: PTFE / Teflon body seals on ball valves
What do you mean with PTFE doby seal? Do you mean the gasket between body and closure? No rubber (FKM or NBR ORings) ?
Which internal bores are you searching for?

The selection of seal materials for ball valves shall be based on actual maximum and minimum operating temperatures of the valves, pressure fluid composition and chemical product used.
And it is not based on the Line class pressure / temperature design conditions.
