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 EPV proportional valve has standard and manifold mounting options, a variety of orifice sizes and control voltage ranges, and three different electrical connectors. Performance curves for two ...

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 ...

There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...

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, ...

Most modern variable valve-timing (VVT) systems use a cam phaser that rotates the position of each cam­shaft relative to the timing chain. Think of making a record turntable go faster or slower by ...

Every aspect of an engine is a compromise: torque for horsepower, efficiency for emissions, performance for fuel economy, compression for octane tolerance. During the evolution of the internal ...
