High-grade ductile cast iron body with epoxy powder coating, excellent corrosion and rust resistance, adapts to long-term outdoor and sewage working environments.
A swing-type structure with a rubber-sealed disc realizes soft sealing and zero leakage, effectively prevents medium backflow, and protects pipeline equipment.
Low fluid resistance design, smooth medium passage, and small pressure loss during forward flow improve pipeline operation efficiency and save energy.
Automatic opening and closing driven by medium pressure, no manual operation required, flexible disc movement, stable, and no water hammer during closing.
Standard flanged connection with universal dimensions matches various standard pipeline flanges, convenient for on-site installation, disassembly, and maintenance.
Horizontal installation design, wide application range, suitable for water supply, drainage, sewage treatment, HVAC, and other industrial liquid pipelines.
Robust integral structure with reliable performance, few moving parts, low failure rate, long service life, and low later maintenance cost.

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.
