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 ...

Flow is controlled by either throttling or diverting it. Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

Modular load-sensing valves control flow and pressure, permitting simpler, more-versatile hydraulics. It's no secret that OEMs want hydraulic controls that simplify mobile-equipment design and are ...

Emerson has released the latest stage of its next-generation AVENTICSTM Series XV pneumatic valve systems with new flow rates ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.

Among the most dangerous issues facing patients in need of replacement mechanical heart valves is aortic regurgitation —  a ...
