This paper describes a new principle for pilot-operated hydraulic relief valves. The new, patented feature enables pressure relief valves to not only limit a pressure differential, but also to limit ...

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 ...

(MENAFN- GetNews) In hydraulic systems, pressure is a critical parameter that determines whether equipment can operate stably and safely. Excessively high pressure may cause pipeline bursts and ...

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 ...

Directional spool valves, such as this PSL model from HAWE, designed for use with constant delivery pumps, are key to many hydraulic control systems. There are three ways to move the spool, cartridge, ...

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, ...

A solenoid valve is an industrial device controlled by electromagnetism which controls fluids, adjusting the direction of the medium, flow, speed and other parameters. There are many solenoid valves ...
