In 2015, Rule R66 F allows (among other things) flow control valves as pneumatic components. Festo's page of one-way flow control valves describes the same thing Chris is describing - allowing free air flow one direction, throttled flow the other. There does not seem to be a rule allowing check valves, which allow air to travel in one direction but completely prevent airflow in the other direction. Apart from the interface between an external compressor and the robot, it is difficult to come up with an application for a check valve that complies with 2015's rule R78, which has been a game rule for some time:

If the compressor is not used on the ROBOT, then an additional pressure vent plug must be connected to the high-pressure portion of the pneumatic circuit off-board the ROBOT with the compressor (see R68).
