VITON GLT SEALS FOR Valves for 16000 PPM H2S ( 1.6% )and 6% CO2

Dear Rana,

As most of the FKM (Fluorocarbon rubbers) and Viton GLT is also the proprietary materials of Dupont, Dupont's recommendation is the best to follow. Especially also of considering the sealing requirement. Also check ASTM D1330. For sealing check ASTM F607. Also check at the this link for more info and guidance. This supplier is quit well know in the valve industry.

Personally I will not prefer to go for Viton GLT for your application. Lastly, it would be advicable to remove your company internal communications. OR could be trimmed out to avoid uneasy situations to you in your company on possible misuse of the same. Pl. take it in the right spirit.

With regards,
Kannan.

But One vendor is recommending to use the VITON GLT seals by OLDRATI (tested by Bodycote ) as per attached test certificates.Some recommendations regarding acceptance criteria are given in attachede-mail extracted from one Dupont site Questions. Experts are requested to kindly guide and give their opinion VITON GLT could be a acceptable choice.Also please if this forum is not for such kind of questions then pleasetell me so that questions I would not post any questions related valves& its internals.
