How is electronic control of fluid power evolving?
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 […]
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 […]
Modular load-sensing sectional mobile valve from Eaton offers flexible design
Power management company Eaton has announced the newest addition to its line of load-sensing sectional mobile valves, the CLS 180. Featuring a highly modular design, the flexible valve helps designers improve machine performance in a variety of mobile equipment for the construction, refuse, agriculture and marine markets. Eaton’s new CLS 180 load-sensing sectional mobile valve […]
Load-holding valves ensure safety in mobile equipment
Load holding valves from Valvole America are available in a very wide range of cartridges or assembled into valve blocks. They secure the last commanded position of an actuator by preventing fluid from escaping work chambers, with “zero” leakage. They ensure low leakage when closed, with less than 5 drops/min when the valve closed with […]
Error prevention at the source: Proportional valves with on-board electronics
On-board electronics (OBE) is the direct and best way to correct nonlinear behavior of a valve, according to officials at Argo-Hytos, Zug, Switzerland. Direct-acting proportional control valves with integrated digital OBE allows fine control of valve spool position and movement. Incorporating a sensor and electronics into the valve body enables a control loop within the […]
