Re: Check valves that trigger at a certain pressure?

What you are looking for is called a back pressure valve. The simpler ones are essentially a check valve with either an adjustable spring tension or preset to open at the desired pressure. "back pressure valves" were not a listed legal component under 2016 rules. "Check valves" were listed components and legal under 2016 rules. A definition thing. In any case it would have to be plumbed to meet the other rules, as Al said. The relief valve required on the robot is actually a check valve with adjustable opening pressure.
