Yuken Type MPW MPA MPB Modular Valve | MPW-06-2-30 MCT-03 MRA-03 | Pilot Check

Yuken Type MPW, MPA & MPB Modular Pilot Check Valves

Product Overview: The Yuken Type Modular Valve Series represents the benchmark for compact integration in hydraulic systems. Utilizing a standard sandwich plate design that complies with ISO 4401 mounting standards, these valves are installed directly beneath directional control valves to provide precise position locking and flow control for hydraulic actuators.

This category includes the core pilot-operated check valves MPW (Dual-port), MPA (Port A), MPB (Port B), alongside the MCT throttle valves and MRA reducing/check valves. Ranging from sizes 03 (NG10) to 06 (NG22), these components fulfill the performance requirements of complex hydraulic circuits.

Key Technical Advantages:

• Zero-Leakage Load Holding (MPW/MPA/MPB): Hardened and precision-ground poppets ensure a drop-tight seal during extended pressure-holding periods, effectively eliminating cylinder drift.

• Compact Integrated Design: Modular sandwich mounting eliminates complex piping, significantly reducing potential leak points and minimizing the overall footprint of the hydraulic power unit.

• High-Response Regulation (MRA/MCT): The MCT series provides precise flow throttling, while the MRA offers pressure reduction with free reverse flow, ensuring smooth system operation.

• Heavy-Duty Durability: Rated for operating pressures up to 25 MPa – 31.5 MPa, ideal for machine tools, brick presses, and metallurgical machinery.
