Not sure if it's working correctly; it appears to be taking longer than before to reach desired pressure.
E.g.
The recipe calls for 20mT strike step for 2s before returning to 10mT for the plasma, but the valve actually opens rather than closes and the pressure drops to 1mT and wobbles for several seconds, before finally stabilizing at 10mT.
