Why Care Where Your Card is Made?

Because where it’s built determines whether your data survives the shoot. For 40 years, Delkin has manufactured high-reliability industrial storage in Poway, CA, USA. We build the Valor PRO® CFexpress™ 4.0 Type B card in that exact same facility using IPC Class 3 manufacturing workmanship standards — the highest, most rigorous tier in electronics.

The Truth About
Other Brands

Standard memory cards are built to mass-market commercial standards (Class 2), which tolerate hidden internal defects. Valor PRO® CFexpress™ 4.0 Type B cards are held to aerospace and medical requirements. It means “performance-on-demand” for mission-critical data when failure is not an option.

Uncompromising
Chain of Custody

USA assembly means total supply chain integrity. You get guaranteed authentic parts, verified firmware, full traceability and zero risk of counterfeit foreign components. By keeping design, assembly, and validation close to home, Delkin maintains direct oversight of every stage of development.

Aerospace
Ruggedness

Every card is uniquely serialized and reinforced using an industrial underfill process. By mechanically bonding the chips to the PCB rather than just electrically attaching them, the Valor PRO® CFexpress™ 4.0 Type B card is physically armored against severe drops, intense vibration, and heavy-duty field use.

Designed, Tested & Assembled in the USA

The Valor PRO® CFexpress™ 4.0 Type B card is designed, assembled, and extensively validated in Poway, CA. Our engineering team developed and refined every aspect of the card’s performance in-house, allowing us to maintain exceptional quality standards and deliver a storage solution optimized for the needs of professional photographers, filmmakers, and content creators. This hands-on approach enables tighter control over component selection, manufacturing consistency, and performance validation, helping ensure dependable operation in even the most demanding shooting environments.

Technologically Advanced Speeds

Capture flawless cinema-quality 8K, 6K & 4K high frame rate RAW video at lightning-fast speeds — up to 3000 MB/s. Engineered for professional creators, the Valor PRO® CFexpress™ 4.0 Type B card is optimized to maintain consistent performance during extended recording sessions, helping prevent dropped frames, buffering, or interruptions when every moment matters. Whether capturing fast-paced action, cinematic productions, wildlife photography, or live events, the card provides the speed and reliability needed to keep up with your creativity and your camera’s full potential.

Streamlined Workflow

The Valor PRO® CFexpress™ 4.0 Type B card is designed to accelerate every stage of your workflow by dramatically reducing transfer times from card to computer. Boasting transfer speeds up to 3700 MB/s, high-speed data offloading allows photographers, videographers, and content creators to quickly access, organize, edit, and deliver their work without unnecessary delays. Whether you’re transferring thousands of RAW images from a full-day shoot or moving massive 8K video files into post-production, the Valor PRO® card helps eliminate bottlenecks that can slow productivity.

Pair the card with one of Delkin’s high-performance CFexpress™ Type B memory card readers to unlock its full transfer potential and keep your projects moving from capture to final delivery with maximum efficiency.
