Steam jackets
(OP)
Dear All,
Is it technically POSSIBLE to provide Steam Jacket on a lug style butterfly valve for operating conditions in my refinery to keep the valve body hot and avoid crystallization (solidification of the service fluid H2S which cause stuck for the valve)
Thanks in advance for your feedback & concern.

RE: Steam jackets
Please find attached (last page). Yes, it is possible.

All valves will last for years, except the ones that were poorly manufactured; are still wrongly operated and or were wrongly selected

RE: Steam jackets
Perhaps flushing with a slightly pressurized inert gas (or heat tracing) the stem bearing and/or packing areas may be enough, in many cases, to avoid the build-up of sticking Sulphur compounds.
