Most design engineers select pneumatic control valves based on performance data published by the valve manufacturer. Usually the key performance factor is how much air a particular valve can flow.

Directional valves such as Parker Hannifin's B3G-Series threeway (left) and four-way valves are often used to control pneumatic operations.

Due to the constant flow of air, the valve becomes clogged over time and needs cleaning. A clogged valve will result in several symptoms indicating that the idle air control valve is not functioning ...

Emerson has released the latest stage of its next-generation AVENTICSTM Series XV pneumatic valve systems with new flow rates, configurations, accessories, UL certifications and more.
