Product Overview

The DUPLOMATIC MZD4/50 is a high-performance proportional pressure reducing valve engineered for precise, infinitely variable control of secondary circuit pressure in industrial hydraulic systems. Manufactured by Duplomatic MS, a globally recognized leader in fluid power technology, the MZD4 series utilizes a robust proportional solenoid actuator acting directly on a precision-machined control spool. This design enables the valve to reduce a higher primary inlet pressure to a stable, electrically modulated outlet pressure that is directly proportional to the input current. Unlike fixed pressure reducing valves, the MZD4/50 offers dynamic response and repeatability, making it an essential component for systems requiring electronic pressure regulation, soft-start/stop ramping, and multi-actuator load management. It is specifically configured for subplate mounting and is widely deployed in complex hydraulic power units, testing rigs, and automated manufacturing lines where accurate force or torque control is critical.

Engineering Features & Advantages

  • Precision Proportional Control: The MZD4/50 spool is specifically contoured to provide a linear relationship between solenoid current and reduced outlet pressure, ensuring smooth, stepless adjustment for delicate clamping or force-control operations.
  • Integrated Pressure Compensation: Features an internal compensator that maintains the set reduced pressure regardless of fluctuations in the primary inlet pressure or flow demand, ensuring stable actuator performance.
  • Industrial Reliability: Built with a hardened, wear-resistant steel spool and sleeve assembly, the valve is designed for continuous duty in high-cycle industrial environments, offering excellent resistance to fluid contamination and thermal drift.
  • Direct Fit Replacement: Manufactured to exact Duplomatic MS dimensional and functional standards, ensuring seamless drop-in compatibility with existing CETOP 3 manifolds and original OEM part numbers.
  • Low Noise & Minimal Pressure Drop: Optimized internal flow passages reduce turbulence and energy loss, contributing to lower system noise levels and higher overall hydraulic efficiency.
