Product Description
Yuken Type MR & MC Series Modular Pressure Control Valves
Product Overview: The MR and MC Series are sandwich-plate (modular) pressure control valves designed to simplify hydraulic system plumbing. Fully compliant with ISO 4401 mounting standards, these valves cover both Size 02 (NG6) and Size 03 (NG10) footprints. By stacking the valve directly beneath a directional valve, users can achieve precise pressure regulation for specific ports (P, A, or B) without additional piping, significantly reducing the size of the hydraulic power unit.
This category features essential models: including the MR-03P modular reducing valve and the MC-02PB, MC-03P, and MC-02AB modular relief valves for various port combinations. With exceptional pressure stability and high-sensitivity adjustment bolts, these valves are the premier choice for industrial machine tools, die-casting machines, hydraulic power units (HPUs), and automated clamping systems.
Key Technical Advantages:
Space-Saving Design: The modular sandwich structure eliminates complex manifold machining and piping, greatly reducing leakage risks and saving installation space.
High-Precision Regulation: Advanced spring and damping designs ensure constant pressure at the controlled port even under fluctuating flow conditions.
Durability & Responsiveness: Precision-ground and hardened spools deliver fast response times and superior contamination resistance, built for 24/7 heavy-duty operation.
Versatile Port Configurations: Supports pressure regulation for P-port, A-port, B-port, or AB-ports combined, meeting diverse hydraulic circuit logic requirements.
