Key features

Manufactured from high-grade stainless steel or alloy steel, with excellent wear and corrosion resistance, and stable performance in various corrosive and high-pressure industrial working conditions.

High-precision CNC compound machining and strict dimensional tolerance control up to IT6-IT7 grade ensure a high degree of matching with the valve core and shaft parts.

Mirror-polished inner and outer surfaces, low friction coefficient, effectively reduce wear during relative movement, greatly extending the service life of the whole assembly.

Integrated flange positioning base design, accurate axial positioning, and firm and reliable assembly effectively avoid displacement during long-term high-frequency operation.

Side notch structure with precise machining perfectly matches the fluid channel design, ensuring smooth medium circulation and stable flow control performance.

Strict full-process quality control, 100% dimensional inspection for each piece, stable batch consistency, meets high-end industrial equipment supporting standards.

Strong customization capability, can produce various sizes, materials, and structural sleeves strictly according to customer drawings, and adapts to different equipment models.

Excellent mechanical properties; can withstand long-term high pressure and impact load, suitable for heavy-duty hydraulic and industrial fluid equipment.

AI-Powered supplier vetting

SummaryThe supplier presents itself as an ODM/OEM partner serving power generation, water treatment, petrochemical, and industrial automation markets. It reports flexible customization, 3D design services, recent product development, quality assurance, documented corrective-action and complaint-handling procedures, and approximately six years of export experience with 31%–40% of sales from exports. It also states membership in the China Valve Industry Association and qualification as a National Power System supplier. However, it reports no valid manufacturing-capacity contract with related subcontractors, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. Material traceability is absent, and the supplied financial records show zero values, limiting confidence in financial credibility. Customer-specific cases are not provided.

Supplier typeThe supplier describes itself as an ODM/OEM partner for power generation, water treatment, petrochemical, and industrial automation applications. Its stated business scope also includes waste processing, construction and metal materials, office equipment, surveillance, networking, and information-security equipment, indicating a broad and potentially diversified profile.

CertificationsThe supplier explicitly states that it is a member of the China Valve Industry Association and a qualified supplier for the National Power System. These are stated industry affiliations and qualification claims, although no certificate numbers, validity dates, or supporting documents are provided.

Financial creditThe supplied financial information reports zero operating revenue, costs, profits, cash receipts, cash inflows, cash outflows, and current ratio for the stated periods. These records do not establish financial strength and create a material basis for concern, although the data alone does not explain whether the values reflect inactive operations, reporting limitations, or another issue.

R&D capabilityThe supplier reports 3D software design services and states that it introduced new products during the past year. This provides explicit evidence of active product-development capability.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full and minor customization, flexible customization, and 3D software design services. Its ODM/OEM positioning further supports the conclusion that it is structured to handle customer-specific requirements.
