Some plumbing problems definitely call for pro-grade expertise, but fixing a water shut-off valve leak isn’t one of them.

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

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

They should be easy to operate. In order to insure that valves perform up to these expectations, valve manufacturers generally specify or recommend that valves be installed per their instructions. For ...

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 ...

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

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 ...

A small addition to your shower head can save you time, money, and water: a simple shutoff valve can toggle the water flow off and on without undoing your carefully-calibrated mix of hot and cold on ...

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, ...

Portland General Electric (PGE) and The Confederated Tribes of Warm Springs (CTWS) are undertaking a complex project to ...
