Im trying to determine what seat class would be the best to use on a non slam check valve. The service is CO2 on the discharge of a compressor. The design conditions for this valve are 270 F / 1113 psig and will have a max flow rate of 38190 lbs/hr.

EN 12266 gives different leackage classes.
A metal-to-metal sealing non-slam (nozzle) check valve should guarantee class C in acc. with EN 12266

My focus is on valve stockists in the us and uk who supply duplex and super duplex valves, and inconel and hastelloy valves, plus titanium, alloy 20 and 904L valves.
