Does anybody know what the recommended cracking pressure should be for a check-valve that mounts between the filler receptacle and the cylinder on the filling circuit should be? I used this one: http://www.swagelok.com/search/produ...S-CHS4-10-SC11
which has a 10 psi cracking pressure, and it sounds like it might be fluttering at times due to minor pressure harmonics in the line while running as the pressure in the system on the main supply circuit drops vs pressure in the filler circuit (between filler receptacle and check valve). I am thinking I may need a check valve with like say a 50 psi cracking pressure or more, but if somebody knows the official spec on this I would definitely like to adhere to that, before I spend $45 bucks on a check valve.
