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.

How Flow Control Valves Work Flow control valves have a valve stem that moves up or down inside the valve body, causing the needle, or sealing element at the end of the stem, to restrict the flow of ...

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.

It is also possible to manage control valve characteristic requirements through the valve positioner. Control valve positioners can typically transform a linear control valve flow characteristic to a ...

You have likely heard of variable valve timing by one of the names manufacturers have for the system, such as VVT-i or VTEC. So what is it and what does it do?

What are 3/2 valves? 3/2 valves or 3 port valves are directional control valves that manage the flow of compressed air in pneumatic systems. They work like a switch.

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 ...
