How to choose a valve for overheated steam of a boiler? (250ºC and 300psi) 1

[cmcmcm]

Hello, I've been looking for valves which can work at high temperatures (at most 250ºC), I'm not too worried about the pressure, but valves which can resist that pressure generally don't resist that temperature, the diameter I'm looking for is 2". Thanks!

The pressure and temperature are trivial compared to those found in power generation and the process industries, so suitable valves almost certainly exist. What function do you need the valve to perform - control, relief, isolation, letdown...?

Wherever steam control is involved you should search for companies with longterm experience with steam components, and stick with their products. Brand names could for instance be Gestra, Spirax Sarco, Velan, - and a great many others. Suggstion : search directly on internet for 'steam control valves' (even if you need other types). High quality products are always best when handling steam.

Thanks a lot for the responses, I want to find a check valve for purging steam.
