Important Pneumatic Valve Specifications

A pneumatic valve controls the rate of flow, pressure, & direction of compressed air. These devices require the force of compressed air to function and transmit power. Pneumatic valves are commonly used and found in many applications. Compressed air pushes a diaphragm or piston (depending on the type of valve used), which activates the valve. Where the valve is used within the system determines if the valve provides open or closed functions. Many types of valves exist to suit the individual needs of specific applications. Although the core function of all valves is the same, the individual characteristics of each differ: do not use valves interchangeably. The most commonly used valves include:

• Flow Control Pneumatic Valves
• Directional Control Pneumatic Valves
• Two-Way Directional Control Pneumatic Valves
• Three-Position Four-Way Directional Control Valves

Several specifications are considered to determine the best type of valve for your specific application. Below, we want to highlight the most important. For more information, you should not hesitate to reach out to our talented team.

Important Pnuematic Valve Specifications

Flow Capacity – The exact measurement of the valve capacity for moving air.

Operating Pressure – You need a properly rated operating pressure valve for optimal performance.

Response Time – The total time needed for a valve to activate.

Port Size – This may be a given, but you need to get valves with the proper thread style and port size to fit within the pneumatic control system.

Operating Medium – The type of media the valve can safely and efficiently process (most often compressed air).
