200 psi check valves?

Call me ignorant, btu I cannot find any push type 3/8 quick connect check valves that handle 200 psi. My system operates at 145-175 psi, and I want to put a check valve between the vu4 and air tank, so if tank loses pressure the system doesnt backflow. 

Alll the ones ive found are max 150 psi.

for anyoen insterested-the best way to do it is get an npt-npt check valve. 100-6000 psi range, all under 20$.
I have an npt to push to connect coming out of my tank for the main feed line, so Im jsut putting the check valve in between those components.
