New ZL Series proportional flow control valves from HydraForce Inc. (Lincolnshire, IL) are internally pressure-compensated and operate in two directions. "The valves provide identical flow vs current ...

Abstract: The proportional directional valve is a key component in electro-hydraulic control systems; however, existing solutions face structural and functional challenges. The mechanical feedback ...

Abstract: An interleaved three-level bi-directional DC-DC converter topology was proposed for high voltage, high power applications in the paper, which has simple structure and is suitable for single ...
