Fairchild Model 4516A Pneumatic Volume Booster

Description
The Fairchild Model 4516A Pneumatic Volume Booster, part of the 4500 Series, is engineered to provide high flow capacity and fast response in pneumatic control systems. Its pilot-operated regulator design allows it to handle supply pressures up to 250 psig (17 BAR) while maintaining precise signal-to-output pressure ratios. Compact, rugged, and highly reliable, this volume booster is ideal for improving the speed and responsiveness of control valves and other pneumatic actuators.
