The idle air control valve (IACV) is a device attached to the throttle body that helps keep the engine of a vehicle running without throttle input, such as when the car is idling in traffic or parked ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.

Intro: A graph of your car’s idle speed shouldn’t resemble architectural plans for a new Cedar Point roller coaster. Once the car warms up to normal operating temperature, it should run in a smooth ...

The committee will study current and potential methodologies and standards, including regulatory criteria, for deciding when an automatic shutoff valve, remote controlled valve or other equivalent ...

The ultraminiature PCFCD-1N1 pressure-compensated flow-control valve, with a low-friction diaphragm, is designed to maintain a constant flow rate, regardless of variations. The ultraminiature ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...
