Key features

Made of high-grade HT200 gray iron via precision sand casting, with excellent structural strength and torsion resistance, no deformation or cracking under long-term reciprocating operation.

Integral 3-spoke casting structure with uniform force distribution and stable torque transmission ensures smooth and labor-saving manual operation.

Square center bore design realizes non-slip transmission with a square shaft, accurate torque output, and avoids slipping during high torque operation.

Round rim with smooth surface, comfortable grip, reduces hand fatigue during long-time operation, improves on-site operation experience.

Multiple surface treatment options, including sandblasting, galvanizing, and painting, provide good corrosion resistance adapts to outdoor and humid working conditions.

Standard square bore sizes with strong versatility can be directly matched with most common square shaft valves and machine tool operating mechanisms.

Mature sand casting process, high production efficiency and stable batch quality, cost-effective for large-volume matching orders.

Strong customization capability supports customization of outer diameter, bore size, structure, and logo strictly according to customer drawings and requirements.

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 materials are available for this square bore handwheel?

Standard HT200 gray iron is provided, and ductile iron is also optional for higher strength and impact resistance requirements.

Q:Can you customize handwheels with special square bore sizes?

Yes, we support full customization of bore size, outer diameter, and structure strictly according to your drawings and technical requirements.

Q:What surface treatments do you provide for the handwheel?

We offer sandblasting, galvanizing, painting, and other surface treatments to improve corrosion resistance and appearance quality.

Q:What equipment is this cast iron handwheel suitable for?
