Made of high-grade ductile iron through integral casting, with high structural strength and excellent pressure-bearing capacity, and stably works under long-term pipeline pressure.
Surface epoxy resin spraying treatment, excellent corrosion and rust resistance, adapts to humid and water supply working environments, greatly extending service life.
Built-in guide cylinder silent structure, smooth opening and closing without impact, effectively reduces water hammer noise, realizes quiet operation of the pipeline system.
Standard flanged connection design matches international standard flange dimensions, easy to install and disassemble, reliable sealing performance without leakage.
High-quality rubber sealing ring, good elasticity and aging resistance, ensures zero leakage under rated working pressure, and improves pipeline operation safety.
Only allows one-way medium flow, effectively prevents backflow of pipeline medium, and avoids damage to water pumps and other equipment caused by reverse flow.
Supports vertical installation, compact structure, small installation space required, and can be directly installed on vertical pipeline sections.
Wide application range, widely used in municipal water supply, fire protection pipe networks, building water supply, and industrial circulating water systems.

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.
