High Temp Valve Manufacturer

High Temp Valve Manufacturer

High Temp Valve Manufacturer

(OP)
Can anyone recommend valve manufacturers who make a good high temperature valve.  The temperature that I am looking at is 600 Degrees at 100 psig.  
Thanks

RE: High Temp Valve Manufacturer

What valve pattern?

Orbit is an example but it has a prefered pressure end.  Is bidirectional tight shutoff required? Metal to metal seats are necessary unless someone mentions something interesting.

RE: High Temp Valve Manufacturer

(OP)
Thank you JLSeagull.  Bi-directional shut-off is not required.  

RE: High Temp Valve Manufacturer

High temperature valves typically are OS&Y, outside stem and yoke.  This gets the stem packing away from the heat.  

We use Orbits in your range reguarly.  A Fisher high performace butterfly is also available.  A longtime ago Crane use to have a gate valve with OS&Y.

RE: High Temp Valve Manufacturer

600 degrees F is not bad.  Most any valve with metallurgy better than brass or iron can handle that.  Steel would be fine.  Even the gaskets will work as long as the packing box is either extended to keep the TFE packing cool, or if the seals are Graphite.  

If the valve is operating at 600C, then special metallurgy is necessary.  Stainless (316) minimum, probably inconel stem and seat, and graphite seals.  


Like everything else, it depends upon what material is flowing through the valve and it is necessary to find a material that is compatible with the lading at elevated temps.  

RE: High Temp Valve Manufacturer

If 600F at 100 psi is your design temperature and pressure this application will fit soft seated materials.  Xomox makes plug, ball and butterfly valves that will fit this application. SVF also makes ball valves that could work.

If 600F at 100 psi is your acual temperature and pressure I would suggest using a metal or graphite seated valve.  Bonneti valve makes a graphite seated ball valve.  Adams makes a metal seated butterfly valve.

All these valves shoud give you a Class VI shutoff.

RE: High Temp Valve Manufacturer

If it's ball valves, try Mogas, Valvtechnologies, Argus or Gosco Valves.  All of them should be able to handle those temperatures (600C or 600F)

RE: High Temp Valve Manufacturer

If you need butterfly valves for 600 degrees C. and a step seat design in the valve body,no being necesary a 100 % tight
valve, get in touch with VALVULAS JOLA in SPAIN. Good butterfly valves in refractory cast iron designs.

RE: High Temp Valve Manufacturer

Thank you all for your recommendations.

RE: High Temp Valve Manufacturer

(OP)
Thanks for the help guys.  I ended up going with high temperature Jamesbury valves.

RE: High Temp Valve Manufacturer

How about the ceramic valve? is there anybody has an idea about the ceramic valve performance at this high temp?

RE: High Temp Valve Manufacturer

Bzandy, Ceramics handle high temps quite well except for the annoying little problem of thermal shock.  If they are rocking along red hot, and somebody switches a valve upstream to let a cool process media in, the ceramic can shatter into many, many pieces.
