I want to design Metal seated Ball Valves.

RE: Metal to Metal Seat Ball Valves

Stop at 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.

ilan7,
      as far as I know, NELES is not part of Tyco Group, but belongs to Metso Group.
      See: http://www.metsoautomation.com  and http://jamesbury.smartcats.com/sc_app/default.asp?code= ...   


      For an example of ball valves Manufacturers within Tyco Group, refer to Raimondi (http://www.raimondi.it/index.html) and other brands listed on the left column of the following Tyco Valves & Controls "EMEA" web-page: http://www.tycovalves-eu.com/brands_results.asp?Selection=Raimondi


      Another famous Italian Manufacturer is OMS Saleri: http://www.oms-saleri.it/home.php ...

RE: Metal to Metal Seat Ball Valves

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?
