Key features

High-grade ductile cast iron valve body with full epoxy powder coating, excellent corrosion and rust resistance, suitable for various water and mildly corrosive media working conditions.

High-quality soft rubber sealing seat, with a tight fit to the valve disc, achieves zero-leakage sealing, effectively prevents medium loss, and improves pipeline operating safety.

Worm gear handwheel drive mechanism for labor-saving operation; can precisely adjust the valve opening and meets both on-off and flow regulation requirements of pipelines.

Double-flanged connection structure, firm and reliable installation, strong bearing capacity, especially suitable for large-diameter and medium-high-pressure pipeline systems.

Concentric centerline structure design, small flow resistance, and low fluid pressure loss ensure smooth and efficient medium transmission in the pipeline.

Compact overall structure, small installation space occupation, convenient for on-site installation, disassembly, and later maintenance, with long service life.

Wide application range, suitable for municipal water supply and drainage, sewage treatment, HVAC, chemical industry, and other industrial pipeline 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.

Product Q&A

Q:What material is the body of this flanged butterfly valve?

It is made of high-quality ductile cast iron with a full epoxy powder coating, with good corrosion resistance, suitable for various water pipeline scenarios.

Q:What sealing materials are available for this soft seal butterfly valve?

A standard EPDM seal is provided, and NBR, PTFE, and other sealing materials are optional to adapt to different media and working temperature conditions.

Q:What is the advantage of worm gear drive compared with lever drive?

A worm gear drive is more labor-saving, can precisely adjust the valve opening, and is more suitable for large-diameter valves and occasions requiring flow regulation.

Q:What pressure ratings and flange standards are available?

Standard PN10 and PN16 pressure ratings, supporting DIN, ANSI, JIS, and other flange standards to meet different regional pipeline installation requirements.

Q:Can this butterfly valve be used for flow regulation?

Yes, the worm gear structure supports stepless opening adjustment, which can be used for both pipeline on-off control and medium flow regulation.
