Metal to Metal Seat Ball Valves

[cadymp]

I want to design Metal seated Ball Valves.
I had designed & validated Soft seated Ball valves ( Floating /Trunnion mounted / 1, 2 & 3Pc.). But not having much idea about metal seated valves.
Please tell me about good handbooks or Literature or websites from where i will get data. Mainly about seat design, Materials of seals to use. Also about torque calculation of these type of seats.

thanks.

Stop at

http://www.fisher.com

and look at the V-300 and CV-500 with metal seals. One of Tyco companies is NELES from Finland and they are one of the experts in metal seal ball valves.

as far as I know, NELES is not part of Tyco Group, but belongs to Metso Group.

The toughest metal seated ball valves are manufactured for the power industry, drains and blowdown, on-off service. Look for information on Union Tech, Mogas, Valve Technology. These guys have been in the business quite a while.

What do you mean by design? Are you "making" a new valve? Or do you mean, you want to select one for use?
