Description
The Youli MB-3/1S-3/161L/E-8 Monoblock Directional Control Valve is a 1-section, 1-spool hydraulic valve designed to control one double-acting hydraulic function in mobile and industrial applications. Rated for 12 GPM nominal flow and up to 4,600 PSI maximum operating pressure, this valve features a 3-position, double-acting spool with A and B work ports blocked in neutral, a direct-acting adjustable relief valve with a 900–2,900 PSI adjustment range, SAE #8 ports, a detented manual lever, and an open-center circuit. The detented lever holds the spool in positions 1, neutral, or 2 without spring return, allowing the selected valve position to remain engaged until the operator manually moves the lever. Its compact monoblock construction integrates the valve components into a one-piece body, simplifying installation and plumbing while reducing potential external leak points.
The MB-3/1S-3/161L/E-8 1-station monoblock valve is well suited for controlling a single double-acting hydraulic cylinder, motor, or other bidirectional hydraulic function where a maintained, detented spool position is required. Warning: This valve does not automatically spring-return to neutral; the lever remains in its selected detent position until manually repositioned. Confirm that maintained operation is appropriate and safe for the equipment before use. Hydraulic systems operate under high pressure and can cause serious injury. The 4,600 PSI rating is the valve's maximum operating pressure and should not be confused with the installed relief valve's 900–2,900 PSI adjustment range. Always verify system flow, working pressure, relief setting, port configuration, spool function, fluid compatibility, and circuit requirements before installation, and fully depressurize and secure the hydraulic system before installation, adjustment, maintenance, or repair
