MRP / MPB / MPD / MRV Series Modular Hydraulic Valves

Product Overview: The Modular Valve Series is a cornerstone of modern integrated hydraulic systems. Designed with standard ISO 4401 interfaces, these valves stack directly between the directional valve and the subplate, enabling pressure regulation, reduction, or relief without complex piping. The MRP/MPB series serves as modular reducing valves, protecting actuators by lowering pressure in specific branch circuits, while the MRV series acts as a modular relief valve, providing critical overload protection. Their compact design not only reduces the overall footprint of the hydraulic power unit but also significantly minimizes potential leak points.

Featured models: MRP-01-C-5G-BJ, MRP-01-H-30, MRP-03-H-10T, MRP-03-H-20, MPB-06-4-30, MPD-06, and MRV-02-B-3-B.

Key Technical Advantages:

• Highly Integrated Design: Modular stacking eliminates vibration risks associated with external piping, resulting in a cleaner and more compact system layout.

• Precise Pressure Regulation: Equipped with high-precision adjustment bolts and robust springs, ensuring a stable set pressure across various flow conditions.

• Comprehensive Bore Sizes: Supports a full range of sizes from 01 (NG6) to 06 (NG25), meeting the flow requirements of large-scale industrial systems.

• Excellent Dynamic Performance: Optimized internal galleries reduce pressure drop and provide rapid response times to handle transient system pressure spikes.
