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 ...

The piSAVE sense is a flow-control/check valve for suction cups. It works in any orientation, is dirt tolerant, and increases vacuum flow through the valve when vacuum level drops to compensate for ...

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, ...

In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...

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 ...

A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...

Scaling is one of the most frequently occurring problems in geothermal power plants and can prohibit the control of well flow if it builds in the well or wellhead. At HS Energy on the Reykjanes ...

QFCL has secured an order worth ₹23.55 crore from Garden Reach Shipbuilders & Engineers Ltd (GRSE) for the supply of valves & ...

At the heart of modern electronics are transistors, which act like valves to direct the flow of electrons. Now researchers at the University of California at Berkeley have created the first ...
