Nov 18, 2009 · low cracking pressure check valve 5. i'm looking for a source for spring loaded check valves with a cracking pressure less than 5" wc (0.18 psi) for nitrogen service. 316ss/ptfe construction will suffice. temperature is 040c. sizes could range from 1/4" tubing to nps 2 cl 150 flanged. so far the lowest cp i've found is 1/3 psi. thanks for any help. donf.
