MSW-03-Y-40 Yuken Check / Throttle Valve
The Yuken MSW-03-Y-40 is a 03-series stackable modular throttle and check valve designed for precise flow speed control and free reverse flow prevention in high-pressure hydraulic systems. Operating on both "A" and "B" service lines in a "meter-in" control configuration, this valve allows independent regulation of actuator speed in both directions while permitting unrestricted return flow.
Engineered with standardized ISO 4401-AC-05-4-A (NG10) mounting surfaces, the MSW-03-Y-40 eliminates individual piping requirements by stacking directly beneath directional control valves and other modular components. Fine flow adjustments are made via calibrated adjustment knobs, ensuring reliable speed regulation for machine tools, industrial presses, and automated hydraulic machinery.
