Product Overview
The EATON 421AA00564C is a high-performance Vickers solenoid-operated directional control valve engineered for precise flow direction management in demanding industrial hydraulic circuits. As part of the renowned Vickers directional valve family, this model utilizes a robust spool-and-sleeve design actuated by a wet-armature AC or DC solenoid, delivering reliable shifting performance and leak-free operation. The 421AA00564C is configured as a four-way, three-position valve with a spring-centered neutral position, making it ideal for controlling double-acting cylinders, bidirectional motors, and complex actuator sequencing in high-cycle industrial systems. Its compact, modular construction allows for direct inline mounting or subplate interface, ensuring seamless integration into both new OEM machinery and existing hydraulic power units.
