Electro-hydraulic Valves - A Technical Look
www.moogvalves.comWe have been producing electro-hydraulic servo valves since 1951. Since then, our experts have had countless discus- ... • Low internal leakage losses • Low energy consumption in center position • Dynamics mostly independent from supply pressure • Higher forces than proportional solenoids, thus higher
