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 ...

FLUID POWER CONNECTORS & COMPONENTS ULTRA-MINIATURE PRESSURE COMPENSATED FLOW CONTROL VALVE WITH LOW FRICTION DIAPHRAGM, BESWICK ENGINEERING CO. INC. Some applications need flow control valves that ...

"Hydraulic Control Valves" describes the three main types of control valves and their functions in a hydraulic system. Control valves control the direction, pressure, and flow rate of fluid as it ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

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.

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, ...

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 ...

If you suddenly have the need for a two-way, flow control valve — from a valve-selection standpoint — what kind of questions do you ask yourself? Many, perhaps, don’t ask any questions and may make ...
