High Temperature Butterfly Valves

[dcb2]

Does any one have any vendor leads/information for butterfly valves with a system design of 2300F at 5 PSIG and operating at 1600F at 3 PSIG? The existing valve is an Everest water cooled design that has failed, cracks in the wafer sealing area and with leaks in the water cooling system. The exisitng valves are 10" 150lb ANSI flange design.

Thanks for your help

Consider using a refractory lined slide valve or a Tyco Vannessa valve (ie. triple offset buterfly).

Please take a look, within this Forum, at:

- Thread408-101237 (my post of Aug. 27, 2004) for the VANESSA (and other Manufacturers) websites;

- Thread408-103783 for Tyco Valves & Controls websites.

Hope this helps, 'NGL

Whats the line process medium? I Have used ceramic valves on hot gas duty in the past. Try cvalves@aol.com. in the UK (Cambrian Valves Ltd) They supplied some for hot gas services.
