How does the valve handle scaling and solid precipitation?

The eccentric structure effectively removes scaling obstacles when opening, making it particularly effective for mixed flow transportation prone to scaling.

What is the average lead time for production?

Peak season lead time is one month, while off-season lead time is within 15 workdays.

Key features

Eccentric Wedge Sealing: Double eccentric structure eliminates wear, ensuring zero leakage and reliable sealing for mixed flows.

Bimetallic Construction: Ball and seat use bimetallic materials with anti-corrosion, wear-resistant, and high-strength surfacing.

Top Entry Maintenance: Top-mounted design allows for easy repair and seat replacement without removing the valve from the pipeline.

Extended Service Life: Sealing pair has compensation amount; wear can be adjusted by turning further, avoiding unit scrapping.

Versatile Application: Ideal for steel, aluminum, fiber, pulp, coal ash, and petroleum gas media with solid particles.

High Pressure Rating: Available in nominal pressures from 150lb to 2500lb, suitable for demanding industrial environments.

AI-Powered supplier vetting

SummaryThe supplier manufactures specialized equipment for oil refining and chemical production and also conducts hardware product manufacturing, research and development, sales, and related services. It reports ISO 9001 and ISO 14001 certification, two production lines, six to ten quality-control staff, and six to ten years of total R&D engineer experience. The supplier offers broad customization, OEM, and ODM services, with documented inspection, corrective-action, complaint-handling, and traceability procedures. Export experience is stated as 15 years, with 51%–70% of total sales from exports and self-operated import/export rights. However, it has no overseas agents or branches, warehouses, showrooms, or SDK availability; it also reports no new products in the past year and no valid manufacturing-capacity contract with related subcontractors. Customer cases are not specifically provided.

Supplier typeThe stated business scope includes manufacturing and sales of specialized equipment for oil refining and chemical production, hardware product manufacturing, hardware R&D, and ferrous metal casting. The company description also covers material purchasing, production, inspection, delivery, and after-sales service, indicating a manufacturer with integrated related operations.

CertificationsThe supplier reports holding ISO 9001 and ISO 14001 certifications. These are explicit certifications relevant to quality and environmental management systems.

After-Sales capabilityThe supplier states that its operations include after-sales service and has clear, followed procedures and records for handling customer complaints and corrective and preventive actions. However, it reports no overseas agents or branches and offers overseas services in zero countries, which limits directly evidenced overseas service coverage.

Production capacityThe supplier operates two production lines, maintains six to ten quality-control staff, has in-stock service capacity, and uses documented inspection, supplier assessment, corrective-action, complaint-handling, quality-assurance, and material-traceability procedures. Nevertheless, it reports no valid contract with associated subcontractors for manufacturing capacity, creating a documented weakness in subcontracting governance.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also provides OEM services for well-known brands and ODM services, demonstrating broad stated customization and manufacturing-design support.

Product Q&A

Q:What is the sealing mechanism of this valve?

It uses a double eccentric wedge principle. The ball and seat are separated during rotation, eliminating wear and ensuring tight sealing with zero leakage.

Q:What materials are used for the ball and seat?

The ball is made of bimetallic material with deposited alloys (SS304 base). The seat uses metal face rings with hard contact seals, often combined with non-metallic elastic materials like PTFE or Nylon.

Q:Can the valve seat be replaced easily?

Yes. The top entry design allows for repair on the pipeline. Users can screw off the compression nut to adjust or replace the seat without scrapping the entire unit.

Q:What types of media is this valve suitable for?

It is suitable for media such as steel, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas, water, vapor, and oil.

Q:What are the available nominal pressure ratings?

The valve is available in nominal pressures ranging from 150lb to 2500lb.
