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 VED03M direct-operated four-way proportional-control valves conform to NFPA D03 and ISO 4401 mounting standards. The valves control direction and flow rate based on the current supplied to 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 ...

A new poppet valve for mobile hydraulics is designed to prevent flow in either direction when de-energised, regardless of pressure at either port. New in the Integrated Hydraulics range of two way ...

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, ...
