(Print title: "Cool-Running Hydraulics) </div> <div class="node-body article-body">Heat kills hydraulic systems. That’s why hydraulic oil coolers are widely used in a diverse range of agricultural, mobile, manufacturing, and industrial settings. They remove excess heat generated by energy losses in a system, as well as that from external sources such as engines, furnaces, and even the surrounding environment.</div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/hydraulics/how-select-and-size-hydraulic-oil-coolers" target="_blank">read more</a></p> http://machinedesign.com/hydraulics/how-select-and-size-hydraulic-oil-coolers#comments Hydraulics Wed, 23 Jul 2014 20:31:00 +0000 39671 at http://machinedesign.com Miniature Proportional Valves http://machinedesign.com/hydraulics/miniature-proportional-valves <div class="field-deck"> Sponsored by Humphrey </div> <div class="node-body article-body">What are proportional valves?

Such circuits are often used where the hydraulics must perform more than one task on the same machine. A backhoe with a loader on one side and excavator on the other is an excellent example. Instead of relying on a bank of valves to manage hydraulic power, all the control can now be handled by software.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/hydraulics/electronic-controls-boost-hydraulic-efficiency" target="_blank">read more</a></p> http://machinedesign.com/hydraulics/electronic-controls-boost-hydraulic-efficiency#comments Construction/Off-road Hydraulics Wed, 26 Mar 2014 15:57:00 +0000 35991 at http://machinedesign.com Improving Precision Coating Processes with Low Volume Low Pressure (LVLP) Technology http://machinedesign.com/hydraulics/improving-precision-coating-processes-low-volume-low-pressure-lvlp-technology <div class="field-deck"> Sponsored by Nordson </div> <div class="node-body article-body">Nordson EFD’s white paper “Improving Precision Coating Processes with Low Volume Low Pressure (LVLP) Technology” shows how LVLP </div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/hydraulics/improving-precision-coating-processes-low-volume-low-pressure-lvlp-technology" target="_blank">read more</a></p> http://machinedesign.com/hydraulics/improving-precision-coating-processes-low-volume-low-pressure-lvlp-technology#comments White Papers Hydraulics Mon, 10 Mar 2014 20:30:00 +0000 35301 at http://machinedesign.com How to Handle Changing Fluid Viscosity and the “Full-to-Empty” Effect http://machinedesign.com/hydraulics/how-handle-changing-fluid-viscosity-and-full-empty-effect <div class="field-deck"> Sponsored by Nordson </div> <div class="node-body article-body">Nordson EFD’s paper explains how to maintain consistent shot size in time-pressure dispensing processes as the fluid viscosity and volume of</div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/hydraulics/how-handle-changing-fluid-viscosity-and-full-empty-effect" target="_blank">read more</a></p> http://machinedesign.com/hydraulics/how-handle-changing-fluid-viscosity-and-full-empty-effect#comments White Papers Hydraulics Mon, 10 Mar 2014 20:22:00 +0000 35291 at http://machinedesign.com 500 Hz dispensing valve http://machinedesign.com/hydraulics/500-hz-dispensing-valve <div class="node-body article-body"><p>The Pico xMod is a piezo-actuated dispensing valve for precision applications.
