The automatic expansion valve (AXV) is similar in construction and appearance to the commonly used thermostatic expansion valve (TXV). However, the metering devices operate much differently. The AXV ...

Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

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.

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 ...

Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...

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 ...

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 ...

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 ...

Pneumatic control systems are used in various applications, including: A single acting cylinder (SAC) is a type of pneumatic actuator that produces force and movement in one direction only. It has a ...

Cleaning the idle air control valve (IACV) on your vehicle periodically helps keep carbon and other particles from building up on the valve, which can negatively affect the operation of the car.
