Are there any applications or interest or need for a full bore ball valve that is capable of maintaining bubble tight shut off for 50,000 cycles for steam service in temperatures of up to 1030 degrees F., and with inlet pressures up to 750 psig??

Why do you ask? Are you selling or looking for the right valve? Are you consider developing such a valve? I am interested in the applications for the project at the moment. I have not done much steam lately.

I was interested in full bore ball valves capable of maintaining bubble tight shut off for 50,000 cycles for hot-oil service in temperatures of up to 500 degrees F., and with inlet pressures up to 750 psig. We have Orbit valves, Vanessa valves, PBV, KF and Ring-o valves in this services. Only the Orbits are cycled frequently. They are not bidirectional and only close from one direction.

If this is something that you are selling, what do you have that meets your specs?

John:
I am actually trying to determine if there is a mrket for a product made in Italy and which I would like to market in the states. This is a full bore ball valve avaiable in carbon steel or stainless steel bodies. It has a patented seat made from graphite and stainless steel layers.
More detailsl are available on the web site look for HTB ball valves.

Again, I am looking for applications that would justify promoting this product in USA.
Thanks,

We have a need for an 1 ¼” and possibly 2 each of a 3” ball valve that has metal seats and meets NACE MR0175 SPECIFICATION FOR SOUR GAS SERVICE.

Interesting, very interesting.

Grove-Italia has an outlet in the United States and Canada under Dresser Flow Control. They have marketed and continue to manufacture in the continental United States and Canada, predominently Western Canada, for the oilfield and pipeline transportation industry. The Grove Ball Valve is a trunnion mounted, full bore type, floating seat (hydraulic activated) and come with full NACE compliance. ANSI Class ratings are typically up to and including 900, I have designed others to 1500 under NPS 6 line size, but temperature limitation is 125F or so because of soft seat technology. It is possible to go to 200F, but usage of high priced elastomers greatly detracts from cost effectiveness.

What you have specified, steam (high temperature service) with bubble tight capacity can only be achieved with a truly floating, metal-to-metal, positive seat shut-off thus implying high torque and elevated cracking pressures. Typically this is gas plant application(s) so you will be competing with Orbit, Cooper-Cameron, General Twin, etc. I do wish you the best of luck with your marketing!

I'm not a huge fan of Cesare-Bonetti, others such as Nuovo Peroni have come into the market and not survived. It will be interesting to see how your price marketing the Euro against the American dollar, particularly in view of the fact that European labor costs are much more expensive than those typically experienced in North America.

Hence the need to keep Mexico and South East Asia in the metallurgical, manufacturing game, Free Trade as so to speak. Everyone is into offshore manufacturing, but your transportation to market costs should proove significantly higher in comparison to the competition.

You'll find plenty of competition for severe service valves in this industry. CCI, Xomox, Tyco and Valvetech make similar products for the application.

 
Granted that this Thread is not to be "red flagged" (due to its marketing nature...), probably the right place for it was the "Valve Engineering Forum" (Forum408).
