Often arguments as to whether a linear or equal percentage trim is best are based on the theoretical inherent flow characteristics. Valve rangeability is often stated as simply a deviation of the ...

Choked flow is a poorly understood phenomenon that can affect control valve sizing, along with trim and material specification. This article was originally published in InTech's July/August issue.

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.

Pressure-compensated flow control valves are useful in a variety of hydraulic applications. For example, they benefit situations where it is necessary to maintain a constant speed of operation of a ...

Valves are necessary to operate pneumatic and hydraulic systems. Industrial valve market was valued at USD 67.5 billion in 2017 and is expected to reach USD 85.2 billion by 2023. A gap exists in the ...

Many engineers may wonder if it is possible to have flashing liquid flow in a control valve even if flow is not choked. The short answer is yes, but it is not very common. This article provides a more ...

Abstract: Piezoelectric actuators are particularly interesting in high-speed precision flow control valves due to their fast dynamic response and simple structure. However, concurrently improving the ...

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 ...
