When we want to change the gaskets on valve bonnets, I encounter different dimensions for each brand. Is there a dimension standard for bonnet gaskets in this sector? Or does anyone have experience on this subject?
Hi All,
When we look at the value in the test standarts for Class IV control Valve, metal to metal
The standart says "Max. allowable leakage 0,01% of Valve Rate Capacity" . and i am wondering what is the meaning of "valve capacity" and how can we calculate and the final what except to this...
A lot of diversity has been created by using different oils in the rotating equipment in the existing facility. I want to simplify these oils on a brand / model basis. Is there a study in the literature related to this? How should I proceed?
Thank you for your attention.
