Product Overview
The Wandfluh AS4Z60b-S1269 is a high-performance solenoid-operated directional spool valve engineered by Wandfluh AG, a globally recognized Swiss manufacturer of precision hydraulic components. This 4-way, 3-position (4/3) directional control valve operates on the proven spool-and-sleeve principle, utilizing a precision-ground steel spool that slides within a hardened bore to direct hydraulic flow between ports P, T, A, and B. Actuated by a robust AC/DC solenoid, the valve provides reliable switching of flow paths for controlling double-acting cylinders, bidirectional hydraulic motors, and other linear or rotary actuators. The AS4Z60b series is designed for direct mounting on standard ISO 4401 / CETOP 03 (NG6) subplates and manifolds, making it a versatile building block for industrial hydraulic power and control systems. Its compact design, high flow capacity relative to size, and precise spool metering characteristics make it ideal for demanding machine applications where repeatable directional control and long service life are essential.
