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, ...

SARASOTA, Fla.--(BUSINESS WIRE)--Helios Technologies, Inc. (NYSE: HLIO) (“Helios”), a global leader in highly engineered motion control and electronic controls technology, introduces cartridge valve ...

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 ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

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.

Control valves experience significant reaction loads when they regulate choked flow. The highly restrictive, complex flow path of existing severe-service valves dissipates the forces from ...
