Not much we can say without know what valve you are using and under what conditions you experience the problem

IVN]!

I found linear indications such as cracks on forged valve made low alloy steel after manufacture.

I guess that ploblems were made while manufacturing.

thanks

sk10009,
Are you the manufacturer ? If not, I would suggest you contact them as they may not be aware of the problem, or there is an explaination of the lineir indications that you have observed.
