Check valves for oxygen system

Check valves for oxygen system

(OP)
I am working on an oxygen system providing 51 Bar (gauge)through a pipe of 76mm (roughly 3 inches).Can anyone recommend a type of check valve for this system?


Mostly I have found lift check valves of this size, I have found other designs as well which are less common from

Also it has to be made from stainless steel.

Any suggestions? Thank you

You should specify when ordering 'fat free for oxygen' and use a type closing with spring to obtain 'soft closing' (closed when pressure is equalized on both sides to avoid slamming and pressure peaks)
