Valves are essential elements for controlling fluid system performance. Virtually every fluid-power system requires some type of valve. In a hydraulic system, valves may control pressure, flow to an ...

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 ...

• The first step in selecting a valve is determining its function. • Review Cv or pressure drop when considering one valve versus another. • Don’t overlook maintenance requirements when specifying a ...

"Hydraulic Control Valves" describes the three main types of control valves and their functions in a hydraulic system. Control valves control the direction, pressure, and flow rate of fluid as it ...

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, ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.

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 ...

Learn about the proper location for those valves, managing blowoff steam and turbine exhaust, and more. Very few deaerators utilize vessels that are not constructed and stamped in accordance with ASME ...

The cascading bypass system is perhaps the most common design for managing high-pressure steam in a combined-cycle plant. It is the hot reheat (HRH) bypass valve actuator that defines the valve’s ...
