Contributed by Josh Cosford Although any “bang-bang” valve is one where the valve shifts between two discreet positions, either open or closed, it can also apply to valves with three positions, such as with a 4/3 solenoid operated directional valve. But there are occasions where a true On/Off valve provides the best solutions to a […]
What is a flow divider?
A flow divider is a hydraulic device that, as the name implies, separates flow into two or more parts. This lets a single pump simultaneously power more than one circuit. Two types of proportional flow dividers are the spool version; and the gear or rotary design. Spool dividers split the input flow proportionally into two […]

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, […]
