DWV 4" sch40 rated at 220 psi?

[Jeeperforlife]

I have my next project in planning and I need to pressurize 4" pipe. I can get 4" sch. 40 pipe. It says DWV 220 PSI, I assume it would be good for 120 psi but wanted to get your thoughts.
It wont be used for a spud gun directly but rather used as a large bore 1 foot stroke pneumatic cylinder.

does it have NSF-PW on it?

It may, I did not look for it. I am still learning PVC. Luckily I have access to all the books on it I could want.

well if it says 220psi then that is its rating, so basically its pressure rated pipe that is of a high enough grade to use for water and such.

Thanks, Now to see if it holds up to the external forces I need it to.
