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 ...

A new line of miniature threaded check valves and fixed-flow controls are available in brass or stainless steel. Standard thread sizes are 6/32, 10/32, ¼-20 and 5/16 -24. Both zero differential and ...

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.

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 ...

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 ...

The Tesla valve is a passive check valve with no moving parts. Because it has no moving parts, there is less wear and tear while reducing the risk of clogging. In general, the resistance to flow in ...

Hydraulic systems are mainly used where there is a need to transfer very heavy loads, even at high speeds. Hydraulic systems can be used for both position control and force control (e.g. in hydraulic ...

After more than half a century of performance at Summersville Dam a second fixed cone valve is being replaced. The new valve costing around $800,000 and weighing 35 tons will be put into service by a ...
