very high set pressure ~43500psi

very high set pressure ~43500psi

I'm looking for manufacturers of PSV with set 43500 psi, can you help me?

RE: very high set pressure ~43500psi

That pressure is extreme for SRV. Can you advise more on the application? Service conditions etc.

Per ISO, only the term Safety Valve is used regardless of application or design.

3000 barg? Trying to OPP the sun?

Are you making diamonds from coal?

Good luck,

To a ChE, the glass is always full - 1/2 air and 1/2 water.

RE: very high set pressure ~43500psi

it's a petrochemical application...

met11, RVP seems a right but...
"All models are designed primarily for thermal expansion or low volume relief applications at high pressures
where flow is not critical"
my case isn't thermal expansion

RE: very high set pressure ~43500psi

The relief valve won't really care what your case is. What is the relieving scenario? You're going to get an enormous amount of flow at 43,500 psi regardless of how big the valve is. In the past at our company, we've used the RVP series with the published areas by Autoclave, and a discharge coefficient of 0.14. I think the K was back-calculated based on some of the published flow curves in the literature.

Unfortunately I don't know of any other valves that can go up to that pressure. I checked the normal players (Leser, Farris, Crosby, Flowsafe, Consolidated) and none of them even get close to those pressures. Most Autoclaves that I've seen operating in those pressure ranges always have an extruder-style rupture disc, or very small safety head.

RE: very high set pressure ~43500psi

The only process I know of which runs that high is high pressure polyethylene- basically a bomb which you use to make a product. Amazing that it works at all...
