[PRV >500 BARG]

Dear All,
Does anyone know any PRV company which its valves can handle >500 barg set pressure?

I know Anderson Greenwood Crosby (Emerson) & Leser have gone to 700 bar, but it depends on the size and application. Tai Italy also.

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

I have looked through Crosby. Crosby cant handle.

Yes they can (I was employed in a senior position back in the day). It's not a catalogued item but a special. You need to talk with the right people. Ask for a "Block Body Valve". What size/connections/materials do you require?

Higher than 500 bar can be handeled, but dependent on exact release pressure, fluid, pressure class, tmperature and capacity.
Do you want the PRV to release to release regularily to the low pressure side, or an PSV to release at critical pressure to air?

Please specify.
