Pneumatic Actuator Response | Basic Principles of Control ...

One way to improve valve response in either type of system (full-pneumatic or I/P-driven) is to use a device known as a volume booster to source and vent compressed air for the valve actuator. A “volume booster” is a pneumatic device designed to reproduce a pneumatic pressure signal (1:1 ratio), but with far greater output flow capacity.

A flow control valves main purpose in pneumatics is to regulate the pressure or flow of a fluid. As a part of a pneumatic circuit, a flow control valves function is to reduce the rate of flow in a specific section, which then results in a slower actuator speed.
