Product Overview
The Eaton DGMC 3 AT CW 41 is a modular (sandwich-style) pressure relief valve from the Eaton DGMC series, engineered for direct mounting between a directional control valve and its subplate or manifold in accordance with ISO 4401 / CETOP interface standards. Operating on a balanced poppet, spring-loaded principle, this pilot-operated pressure control valve limits system pressure by diverting excess flow to tank when the preset cracking pressure is exceeded, thereby protecting downstream components from overpressure. The “3” size designation corresponds to NG6 / CETOP 3 mounting, while the “AT” and “CW” codes define the pressure adjustment and adjustment mechanism configuration. As a modular cartridge-style valve, it integrates seamlessly into stacked hydraulic circuits, making it a compact and serviceable solution for pressure regulation in industrial power units and machine tool hydraulic systems.

Engineering Features & Advantages
- Precision Pressure Control: Balanced poppet design delivers accurate, repeatable cracking pressure and stable regulation across the full flow range, minimizing pressure override and system shock.
- Modular Sandwich Construction: Direct NG6 / CETOP 3 interface allows tool-free integration into existing stacked valve assemblies without additional piping or manifold modification.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components resisting wear and contamination-induced drift.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Eaton DGMC series OEM standards, ensuring drop-in interchangeability.
- Compact Footprint: Space-saving modular design reduces overall manifold size and simplifies circuit layout in dense hydraulic power units.
Typical Industrial Applications
The Eaton DGMC 3 AT CW 41 modular pressure relief valve is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tool hydraulic systems, and general industrial power units where reliable overpressure protection and precise pressure regulation are required. Its CETOP 3 modular format makes it particularly suited to stacked directional control valve assemblies in construction, marine,
