By Josh Cosford, Contributing Editor Back in August of 2017, you saw my article Hydraulic symbology 101: Understanding basic fluid power schematics (read it here first, if you haven’t already). I covered basic constituent lines, shapes and their respective symbols. Due to space constraints, I left out some of the major components represented by symbols […]
Proportional solenoid cartridge valve provides precise control in a compact package
Eaton has released the new ESVL9 screw-in cartridge valve (SiCV), a five-way, three-position proportional solenoid valve. Featuring a patent-pending, integrated load-sense check control, the latest solution provides a 21% manifold size reduction compared to the external checks available with many five-ported directional control valves on the market today. “As customers transition from on/off control systems, […]
Safe and reliable control of large flows
The CINDY family of cartridge valves from Bucher Hydraulics, Klettgau, Germany, has been proven for decades in countless industrial and mobile applications. That, according to company officials, is due to features such as extremely low leakage, finger-tip controllability and load-independent cylinder travel behavior. Bucher Hydraulics has now expanded its well-established CINDY technology offerings with the […]
Ross Controls expands into hydraulics with hydraulic safety valve system
Ross Controls introduces its new Hydraulic Block & Bleed valve systems designed for external monitoring, up to Category-4, PL e for safety applications. Ross, who is already known throughout the industry for reliable pneumatic safety-related valves and solutions, now expands upon these strengths to offer solutions for users of hydraulic systems. The Ross Hydraulic Block & Bleed […]
Safety and efficiency in marine applications at SMM 2018
Danfoss will be presenting its complete marine portfolio at SMM 2018 in Hamburg, Germany. From the keel to the bridge, the company’s products can be used everywhere on a ship to make it safer, more efficient and environmentally friendly. The products work together to provide comprehensive solutions for ocean and inland vessels. Danfoss will exhibit its […]
4 takeaways on the economy from Alan Beaulieu’s IEOC presentation
Dr. Alan Beaulieu of ITR Economics gave his usual entertaining and fact-filled talk at the National Fluid Power Association’s annual International Economic Outlook Conference this month. Beaulieu stressed that despite all the fervor, the economy unfolded in a predictable manner — and the economy is bigger than Washington, D.C. He pointed out that the average […]
Customization enhances pressure switch functionality
Pressure switches are often considered commodity items. But for many mission-critical or demanding applications, including high-pressure hydraulics, aerospace, pharmaceuticals and more, a switch may require a custom mechanical design or electrical features that go beyond what commercial off-the-shelf switches can offer. In fact, with a little extra engineering, users can boost a switch’s performance and, […]
Shift in Motion: An innovative propulsion system for mobile machines
Manufacturers and operators of today’s mobile equipment often want a machine that does double duty: provides high tractive effort in the working mode and high maximum velocities when operating in the transport mode. These drivetrain requirements can be met through a wide array of traditional technological concepts, ranging from simple manual transmissions (shifted at standstill) […]
Danfoss wheel loader solutions uplift machine and operator performance
Danfoss Power Solutions is now offering differentiating wheel loader solutions and subsystems, which are proven at our global Application Development Centers (ADCs). The wheel loader subsystem solutions are developed and tested under real-world conditions at our ADCs and are proven to increase productivity and uptime while lowering total cost of ownership by improving efficiency. Our […]
New-generation valve actuation
Proportional hydraulic valves are key components in mobile agricultural and construction machines, as they control motion for a wide variety of functions via cylinders and hydraulic motors. Electrohydraulic actuation is often used to control valve main-spool movement. For lower flows two solenoids can directly actuate the spool, but such arrangements result in high hysteresis and […]
