Vickers DGMC-3 Relief Valve | DGMC-3-AT-CW-41 | DGMC-3-PT-CW-41 | NG6 Sandwich Valve

Vickers DGMC-3 Series Sandwich Relief Valves

Product Overview: The Vickers DGMC Series is a high-performance sandwich-plate relief valve designed with the standard ISO 4401-03 (NG6) mounting interface. As a modular pressure control solution, the DGMC valve allows users to build pressure regulation circuits directly beneath a directional valve without the need for additional piping. Its Sandwich Design significantly saves space and reduces potential leak points in hydraulic manifolds. Whether utilized for P-port limiting (PT Models) or actuator protection on ports A or B (AT/BT Models), the DGMC series provides precise and stable pressure control for industrial and mobile applications.

Featured models on this page include the DGMC-3-AT-CW-41, DGMC-3-PT-CW-41, and the dual-circuit DGMC2-3-AT-GW-BT.

Key Technical Advantages:

• Modular System Integration: Fully compliant with NG6 standards, enabling flexible stacking with other modular components to simplify hydraulic power unit designs.

• Versatile Adjustment Options: Available with CW (Handwheel) or GW (Socket Screw) adjustment types to suit various on-site calibration requirements.

• High Response & Stability: The optimized spool design ensures minimal pressure override during relief operations and excellent repeatability.

• Dual-Circuit Protection: The DGMC2 variants enable independent or cross-over pressure limiting for both A and B ports within a single block, enhancing system compactness.
