Vickers SystemStak™ Modular Stackable Hydraulic Valves

Product Overview: The Vickers SystemStak™ series represents the industry standard for modular hydraulic system design. By stacking multiple control functions (pressure, flow, and directional control) directly beneath a directional control valve, this series eliminates complex piping, drastically reduces power unit size, and minimizes leakage risks. Whether in industrial machine tools, injection molding, or mobile machinery, SystemStak valves provide a highly flexible and compact control solution for Size 3 (NG6) and Size 5 (NG10) standard mounting interfaces.

Featured series include: DGMC (Relief), DGMPC (Pilot Check), DGMFN (Flow Control), DGMR/DGMR1 (Reducing), DGMX2 (Sequence), and DGMC2.

Key Technical Advantages:

• Space-Optimized Design: The stackable configuration allows for multiple functional layers on a single manifold, significantly reducing the system’s physical footprint.

• Tubeless Integration: Eliminates external interconnecting lines between valves, reducing system pressure drop and eradicating potential leak points.

• Full Functional Range: Spans from basic check valves (DGMDC) to complex pilot-operated controls, meeting all circuit logic requirements.

• High-Pressure Reliability: Constructed from high-strength materials, with rated operating pressures typically reaching 31.5 MPa (315 bar).

Detailed Specifications & Parameters:

• Featured Function Matrix:

  • DGMC / DGMC2: Modular relief valves for pressure limitation of systems or specific actuators.

  • DGMPC: Modular pilot-operated check valves for reliable actuator locking.

  • DGMFN: Modular dual-throttle check valves for precise meter-in or meter-out speed control.

  • DGMR / DGMR1: Modular pressure reducing valves, providing stable low-pressure supply to branch circuits.

  • DGMX2: Modular sequence valves to control the operational order of multiple actuators.

• Core Technical Specs:
