Proportion-Air, Inc. Datasheets for Pneumatic Relays and Volume Boosters
Pneumatic relays and volume boosters control output air flow and pressure in response to a pneumatic input signal. They can perform simple functions such as boosting or scaling the output, or use complex reversal, biasing, and math function operators.
