We did use the check valve when we tested it. So I assume if we took it out you would be correct, one side wouldn't be as stiff, but both are as strong. In our case you would have to push back against the piston with a force greater than 160 lbs to create enough backpressure (greater than 60 psi) to force air out of the regulator. Even without the check valve its not really a problem. You have full strength of the piston in both directions. If in the rare occation you would have a force strong enough to force the piston backwards it would move (only in one direction as you stated before) This would happen in a regular pneumatics setup anyway.
