MBP / MBA / MBB Series Modular Pressure Reducing Valves

Product Overview:

The MBP, MBA, and MBB Series are high-performance modular pressure reducing valves specifically designed for secondary circuit pressure control in hydraulic systems. Featuring a stackable modular architecture, these valves can be mounted directly between directional control valves and subplates, enabling branch circuit pressure reduction without additional piping. Whether deriving stable low-pressure lines from high-pressure mains or optimizing space in complex manifolds, this series delivers exceptional regulation linearity and rapid system response.

Featured nominal sizes on this page: 01 (NG6), 03 (NG10), 04 (NG16), and 06 (NG25).

Key Technical Advantages:

• Highly Integrated Design: Compliant with ISO 4401 standard interfaces, significantly reducing the hydraulic unit footprint, eliminating leak points, and lowering assembly costs.

• Versatile Circuit Options: * MBP: Pressure reduction on the P-line.

  • MBA: Pressure reduction on the A-line.

  • MBB: Pressure reduction on the B-line.
