Key features

Double Eccentric Design: Cam-like action reduces seat wear, eliminates deformation, and ensures zero leakage.

Bidirectional Zero Leakage: Assures shut off throughout the full pressure range with no seat contact when open.

Extended Service Life: Disc does not contact seat when open, reducing operating torque and extending seat life.

Anti-Buildup Wiping Action: Prevents material build-up from slurries or suspended solids during closing.

Wide Size Range: Available in sizes from 2 to 60 inches (50-1500mm) depending on pressure class.

Multiple Actuator Options: Supports manual lever, worm gear, electric motor, and pneumatic actuators.

Customizable Sealing: Sealing material can be customized to Metal or Rubber based on specific requirements.

AI-Powered supplier vetting

SummaryAfcon Ningjin Yahua Industries Co., Ltd. is identified as a Chinese limited-company manufacturer/factory specializing in industrial valves and related pipe-fitting products. The supplier reports in-house sand casting and powder-coating lines, a 50,000-square-meter facility, annual valve productivity of 7,000 tons, and peak-season order fulfillment within one month. It holds stated certifications including ISO 9000, ISO 9001, ASME, HSE, ABS, CE, DNV-GL, and LR. Evidence also indicates export activity across Europe, the Middle East, the Americas, Africa, and Asia Pacific, with large projects reportedly installed and customer satisfaction achieved. R&D activity, six to ten R&D engineers, and six to ten quality-control staff support its technical and quality capabilities. However, the provided information does not sufficiently establish after-sales service procedures, financial credibility, or detailed customization capability.

Supplier typeThe supplier is described as both a Manufacturer/Factory and a trade company, with a limited-company structure. Its stated business focus is R&D, design, and manufacturing of industrial valves and related pipe-fitting accessories, indicating a manufacturing-oriented supplier despite the trade-company classification in one record.

CertificationsThe supplier states that it holds ISO 9000, ISO 9001, ASME, HSE, ABS, CE, DNV-GL, and LR certifications or approvals for export needs. These explicitly documented certifications support its quality-management and product-compliance position.

R&D capabilityThe supplier states that it conducts R&D and product research in industrial valves, has six to ten R&D engineers, and is developing innovative fire-safe valves with planned API approval. These statements provide explicit evidence of ongoing innovation activity, although the future API approval is not confirmed as already obtained.

Production capacityProduction capability is supported by in-house sand-casting and powder-coating lines, engineering and manufacturing facilities, a 50,000-square-meter site, reported annual valve productivity of 7,000 tons, and a one-month peak-season fulfillment time. The supplier also reports more than eight to ten years of development and manufacturing experience, indicating established operational capacity.

Client casesThe supplier reports exports to Europe, the Middle East, America, Africa, and Asia Pacific, and states that many large projects were successfully installed with complete customer satisfaction. However, no customer names, project names, order references, or independently verifiable case details are provided.

Product Q&A

Q:What is the sealing performance of this valve?

The double offset design assures bidirectional, zero leakage shut off throughout the full pressure range.

Q:How does the double eccentric design improve durability?

The cam-like action pulls the disc from the seat initially, reducing wear and eliminating deformation. When open, the disc does not contact the seat, extending service life.

Q:What materials are available for the seat?

Seat materials include PTFE, RTFE, 316 SS, Inconel, PTFE+316SS, and RTFE+316SS, offering Class V or VI bubble-tight ratings.

Q:What actuator options are supported?

Options include Manual Lever, Worm Gear Operator, Electric Motor, Pneumatic Double Acting, and Pneumatic Spring Return.

Q:What are the available flange classes and sizes?

Flange classes are ANSI 150, 300, and 600. Sizes range from 2-60 inches (50-1500mm) for Class 150, 2-48 inches for Class 300, and 2-24 inches for Class 600.
