Product Overview
The YUKEN MRB-01-B-30 is a modular pressure reducing valve designed for precise secondary circuit pressure control within industrial hydraulic systems. Manufactured by YUKEN, a globally recognized leader in hydraulic component engineering, this valve belongs to the MRB series of modular reducing valves that mount directly between a directional control valve and a subplate or manifold, eliminating the need for separate piping runs. The MRB-01-B-30 operates on a balanced spool principle, reducing a higher primary supply pressure to a stable, adjustable secondary pressure that feeds downstream actuators or sub-circuits. With a 01 (NG6 / CETOP 3 / ISO 4401-03) interface size and a B-type adjustment mechanism, it delivers reliable pressure regulation for machine tools, injection molding equipment, and other precision industrial hydraulic applications where consistent reduced pressure is critical to process accuracy and component protection.
