Product Overview
The Vickers DGMDC-3-Y-PK-41 (part number 694415) is a modular check valve designed for use within ISO 4401 / CETOP sandwich valve assemblies. Manufactured by Vickers (Eaton), this DGMDC series module is installed between a directional control valve and its subplate or manifold, providing controlled free flow in one direction and positive shut-off in the reverse direction. Its modular sandwich construction allows it to be stacked directly with other DG-series modules without additional piping, making it a core building block for compact, leak-resistant hydraulic circuits in industrial power units and machine tool systems.

Engineering Features & Advantages
- Precision Performance: Spring-biased poppet/seal design delivers low cracking pressure for free flow while ensuring zero-leak shut-off in the blocked direction, protecting actuators from drift and load-induced reverse flow.
- Modular Circuit Flexibility: Sandwich construction integrates directly into DG-series stacks, eliminating external check valve piping, reducing leak points, and simplifying circuit modification or field retrofits.
- Industrial Reliability: Hardened, precision-machined internal components are built for continuous operation under severe industrial conditions, including pressure spikes and high duty cycles.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Vickers OEM standards, including the 694415 catalog reference, for drop-in service replacement.
Typical Industrial Applications
This modular check valve is commonly deployed in plastic injection molding machines, metallurgical and stamping presses, CNC machine tool hydraulic power units, and general industrial manifold assemblies where load holding, reverse-flow prevention, or directional isolation is required within a compact sandwich valve stack.
