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 ...

On/off valves are basically on/off switches for hydraulic systems. They are typically installed in applications where precise position or speed control is not required. Proportional valves adjust flow ...

Before selecting an engineered solution for any fluid control application, it is crucial to understand the unique application and overall value that each ball valve provides. Ball valves come in a ...

Motion-control valves solve troublesome equipment-instability problems. • Overcenter, or motion-control valves, are well suited for load holding and control. • Standard overcenter valves can solve the ...

HVAC systems that regulate temperature and air quality to keep enclosed areas warm in wintertime typically depend on natural gas combustion to sustain boilers, pumps, radiators, meters, and other ...

Identify the forces that act on closure components and actuators. Describe how these forces work in the positioning of closure components. Prepare equations required to determine an actuator (i.e.
