Pneumatic Flow Control Valves

Pneumatic Flow Control Valves | Air Flow Control Valves

Pneumatic flow control valves are used to reduce the rate of flow in a section of a pneumatic circuit, resulting in a slower actuator speed. Unlike a needle valve, a pneumatic flow control valve regulates air flow in only one direction, allowing free flow in the opposite direction.

Selecting the Right Air Flow Control Valve

Flow rate requirements are extremely important when selecting a pneumatic flow control valve for your application. The speed of the related actuator is dependent upon how quickly it can be filled with air at the input and released through the output.
Pneumadyne offers air flow control valves in a range of styles, configurations, and port sizes. If you’re not sure which model is right for your specific application, please don’t hesitate to contact us. Our knowledgeable team will review the needs of your system and help you select the pneumatic flow control valve that best meets your requirements.
See individual product listings for additional information and specifications.


Air Flow Control Valves

Inline flow control valves feature finely threaded stems that allow for gradual adjustment of the controlled flow passing through the valve. The pneumatic system’s air flow enters via the input port, travels through an orifice sized by the tapered stem, and out via the output port. Our pneumatic flow control valves include a bypass check which allows rapid free flow from the output through the input port. Finely threaded stems allow gradual adjustment of controlled flow to match system requirements.
We offer two types of air flow control valves. Their selection and placement within a pneumatic circuit will greatly affect the function of an actuator.
  • A meter-in flow control valve (also known as a reverse flow control valve) restricts the flow to an actuator.
  • A meter-out flow control valve regulates the exhaust flow from an actuator. These are the most commonly used air flow control valves.
