Stelliting inside the cages - globe control valves

[Mechsal]

In severe services I know that seat and plug are stellited, but can inside the cages be stellited too??

It is not required... but Sometimes due to the customer requirement, this cannot be avoided.
instead of stelliting hard chrome coating is enough if you can convince the customer with technical clarification.

There are no secrets to success. It is the result of preparation, hard work, and learning from failure.
