Heavy-duty priority flow-control valves provide a simple and efficient way to supply auxiliary hydraulic power to mobile work tools and attachments, such as hydraulic impact hammers, compactors, saws, ...

Unit features a priority valve and an intelligent throttle control system to allow for variable air-on-demand with increased cfm output, while simultaneously providing steady gpm output. The DTM70-H ...

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

VMAC’s Direct-Transmission Mounted Multi-Power System (DTM70-H) is a power-takeoff technology designed for Ford service trucks fitted with hydraulic cranes or other hydraulic components. The DTM70-H ...

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 ...

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 ...

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, ...

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 ...

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 ...
