Pilot Valves and Pneumatic Amplifying Relays
Self-balancing mechanisms consisting solely of a baffle/nozzle detector coupled to a feedback bellows, while functional, are not always practical as

Most pneumatic instruments use a simple but highly sensitive mechanism for converting mechanical motion into variable air pressure: the baffle-and-nozzle
