Ball valve seal material for sour gas
Ball valve seal material for sour gas
(OP)
Hi,
I am looking to purchase a trunnion ball valve for sour gas service at 38C, 285 psig. What would be the best seal material?
The manufacturer has a list of choices:
Viton
HNBR
EPDM
Aflas
Thanks,

maybe you'll find useful to read thread408-201095: Methanol vs Viton seals in valves within this Forum.
If you input your service conditions in the "Application Guides" mentioned therein, you'll probably find the more suitable polymers for your application...
Hope this helps, 'NGL
