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 ...

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 ...

GEMÜ’s process solenoid valve with pressure compensation, the GEMÜ M75, uses a double bellows principle to balance pressure forces, which allows the valve to be used for processes with an operating ...

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 ...

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.

Have you ever dreamed of a refrigeration system that would hold a constant pressure in both the evaporating and condensing sides of the system? What if this constant-pressure system could maintain the ...
