Product Overview
The Danfoss CV3-10-P-0-20 (Part No. 566004) is a high-performance screw-in cartridge check valve engineered for precise flow control within hydraulic circuits. As a member of the Danfoss CV3 series, this valve is designed to allow free flow in one direction while providing zero-leak, leak-tight sealing in the reverse direction. Its 10-size cavity configuration makes it an ideal solution for compact manifold and integrated circuit designs, effectively preventing backflow, load dropping, and pressure spikes in demanding industrial hydraulic systems. The “P” designation indicates a poppet-type construction, offering fast response and reliable sealing even under low-pressure differentials.

Engineering Features & Advantages
- Precision Performance: The poppet-type check valve mechanism ensures fast, reliable sealing with minimal pressure drop in the free-flow direction, maintaining system efficiency and preventing backflow-induced damage.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components and robust cartridge construction that withstands high-pressure cycling and contamination.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Danfoss OEM standards, ensuring drop-in installation into standard 10-size cavities without modification.
- Compact Modular Design: Screw-in cartridge format reduces manifold size and simplifies hydraulic circuit integration, ideal for space-constrained applications.
- Zero-Leak Sealing: Precision-machined poppet and seat deliver leak-tight performance, preventing load drift and energy loss in holding circuits.
Typical Industrial Applications
This cartridge check valve is widely used in heavy industrial scenarios including plastic injection molding machines, metallurgical presses, construction and marine hydraulics, and CNC machine tools. It is particularly suited for load-holding circuits, pump isolation, and directional control manifolds where reliable backflow prevention is critical.
