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 ...

"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 ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

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 ...

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, ...

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 ...

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 Aventics Series 625 Sentronic proportional pressure control valves feature a control deviation of less than 0.5% to deliver accurate, electronic proportional pressure control and provide the ...
