Electrohydraulic or hydroelectric? It’s odd how similar those two compound words are, yet they’re obviously entirely different in meaning. Hydroelectric refers to the production of electricity by way of converting the potential kinetic energy found in conjoined bodies of water of varying height, into electrical energy used by everyone and their hamster. Electrohydraulic is the […]
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, […]
Hydraulic combination valve offers complete motor control for mobile machinery
Webtec, a specialist manufacturer of hydraulic measurement and control products, is unveiling its new CV120 series combination valve that provides a complete solution to hydraulic motor control for mobile machinery. Hydraulic system designers will discover that the compact CV120 reduces both space and pressure drop in machinery used for mining, quarrying, construction and agricultural applications, […]
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 […]
Metal-bellows accumulator handles the extremes
Edge-welded metal bellows accumulators are at the cutting edge of hydro-pneumatic accumulator technology, according to Peter Kloft and Daniel Rau, research and development engineers with HYDAC Technology in Sulzbach/Saar, Germany. Compared with other designs such as diaphragm, bladder and piston accumulators, the gas chamber in metal-bellows units is usually hermetically sealed and the metallic barrier […]
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 […]
How do I specify standard hydraulic manifolds?
By Josh Cosford, Contributing Editor The three most common ways to control hydraulic actuators are with lever valves, cartridge valves or sandwich valves. Lever valves are available as monoblock or stacked valves, and are primarily for directional control. Cartridge valves have nearly infinite possible combinations, but must be used with bodies or custom manifolds. Sandwich […]
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) […]
