Product Overview
The WANDFLUH SDSPM18-FG is a high-performance solenoid-actuated directional spool valve engineered by Wandfluh AG, a globally recognized Swiss manufacturer of precision hydraulic components. Operating on a direct-acting spool principle, this valve controls the start, stop, and direction of hydraulic fluid flow within a circuit by shifting a precision-ground spool via an integrated solenoid actuator. The SDSPM18-FG is designed for demanding industrial hydraulic systems requiring fast response, leak-tight sealing, and reliable directional control of actuators, cylinders, and motors. Its robust construction and precise spool-to-bore clearance ensure minimal internal leakage and consistent switching performance across millions of operating cycles.
