Product Overview
The Vickers DGMPC-3-ABK-BAK-41 (part number 694400) is a modular pilot-operated check valve designed for use in CETOP 3 / NG6 (D03) size manifold and sandwich valve assemblies. Manufactured by Vickers (Eaton), this dual pilot-operated check valve module provides reliable load holding and leak-free blocking of actuator lines in one or both directions until a pilot pressure signal is applied to open the poppet. The DGMPC-3 series is engineered for precise control of cylinder and motor circuits, preventing drift under load and enabling controlled decompression in demanding industrial hydraulic systems.

Engineering Features & Advantages
- Precision Performance: Pilot-operated poppet design delivers leak-free load holding and controlled opening, preventing actuator drift and enabling smooth decompression of trapped pressure.
- Dual Directional Control: ABK / BAK configuration provides pilot-operated check function in both A and B lines, offering flexible circuit design for bidirectional load holding.
- Industrial Reliability: Hardened, precision-ground poppet and seat components ensure long service life and consistent sealing performance under continuous industrial duty cycles.
- Direct Fit Replacement: Exact dimensional and functional compatibility with Vickers DGMPC-3 series modules and standard CETOP 3 / NG6 sandwich assemblies.
- Compact Modular Design: Space-saving sandwich construction simplifies system integration and reduces piping complexity in multi-function manifold stacks.
Typical Industrial Applications
This modular pilot-operated check valve is widely used in plastic injection molding machines, metallurgical presses, CNC machine tools, and construction & marine hydraulic systems. It is particularly suited for circuits requiring load holding, cylinder locking, and prevention of reverse flow in manifold-mounted directional control valve stacks.
