Disabled pressure safety requirements

Hi everyone,
For our robot we are using a pneumatic system in order to run our arm that holds the totes. We saw that there is a safety requirement that the robot should have no pressure in the compressor when it is disabled.

However, our robot doesn't have a digitally accessible valve, only a manual valve for letting the air out of the system. Would this meet the requirement in order to have all the pressure as 0 if we manually release the valve as we take the robot off the field?

Additionally, if it is needed to have a digital pressure release during disabled, how would you recommend we do this? We don't currently have the hardware for a digital valve, and are unsure if a second solenoid is the best way to go. Currently the only way we can release the pressure is by actuating the arm repeatedly which would probably a worse safety hazard since that would open and close our arm mechanism.

Thanks for your help,
Team 8.
