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 ...

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 ...

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, ...

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 ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...

Known as the Rotary Drag valve, the new device represents a major step forward in valve engineering because it combines the best features of ball valves and control valves. Developers of the product ...

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 ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...
