What is the maximum pressure rating for this 24mm ball in a valve?

Pressure resistance depends on seat design, support method, and temperature. Static sealing commonly exceeds 10 MPa. High temperatures reduce pressure capability. For accurate verification, provide your operating parameters and we can assist with evaluation.

For bulk orders, how do you ensure dimensional and performance consistency of each ball?

We use controlled raw materials and standardized molding processes. Each batch is inspected for diameter, roundness, density, and surface quality. Retained samples and lot traceability records ensure stable, reliable batches for repeated valve assembly.

AI-Powered supplier vetting

SummaryZhenjiang Chunhuan Sealing Materials Co., Ltd. (Group) is identified as a manufacturer and trading company with its own export license, 186 employees, and more than 30 years of operating history. It produces PTFE sheets, rods, gaskets, and related plastic products, and reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials. The supplier supports extensive customization and has documented inspection, corrective-action, complaint-handling, and traceability procedures. It reports inventory capability, one-month average lead times in both peak and off-season, and 20 years of export experience. However, it does not provide 3D software design services, has no available SDK, overseas warehouse, overseas showroom, overseas agent or branch, and has not participated in offline trade shows. No valid manufacturing-capacity contract with related subcontractors is reported. Financial information is referenced for 2020–2022, but the provided slices do not disclose sufficient financial results to assess...

Supplier typeThe supplier is explicitly described as both a manufacturer and trading company with its own export license. Its stated activities include manufacturing plastic products and processing machine elements and spare parts, supporting classification as a manufacturing-oriented supplier.

CertificationsThe supplier reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials, while the sustainability-related certification is specified as ISO9001:2015. These stated certifications provide explicit evidence of certification holdings, although the slices do not verify their scope or current validity dates.

After-Sales capabilityThe supplier has clear procedures and followed records for handling customer complaints, as well as corrective and preventive actions. This directly supports an established after-sales issue-management process.

Production capacityThe supplier identifies itself as a manufacturer with 186 employees and established plastic-product production, reports in-stock capability, and states one-month average lead times in both peak and off-season. However, it also reports no valid manufacturing-capacity contract with related subcontractors, so the evidence demonstrates internal production capability but leaves outsourced-capacity controls as a limitation.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. This is direct evidence of a broad customization service range.

Product Q&A

Q:Which chemical media can this ball resist? Is it suitable for high-temperature corrosive fluids?

Pure PTFE resists almost all strong acids, bases, salt solutions, and organic solvents. It does not absorb water or swell, making it ideal for high-temperature corrosive fluid control. However, strong oxidizing acidsshould be avoided.

Q:How does it ensure a reliable seal with the valve seat?

The ball is precision machined with high roundness and surface finish, ensuring uniform contact with the seat for reliable sealing. PTFE's low friction allows low opening torque, while its non-stick nature prevents adhesion to the seat and reduces leakage.

Q:Is this ball FDA-compliant or food-grade?

Pure PTFE grades meet FDA 21 CFR 177.1550 for food contact and can be used in food, pharmaceutical, and potable water systems. Please specify food-grade requirements when ordering, and we will provide batch-specific compliance statements.

Q:Can I customize other diameters or filled reinforced versions?

Yes. We support non-standard diameter customization, from small sizes to larger specifications. Fillers such as carbon fiber, glass fiber, and graphite can be added to improve wear resistance, creep resistance, or thermal conductivity. Filled versions are not FDA-compliant.

Q:What should I pay attention to during installation to avoid damaging the ball surface?

Keep the valve seat clean during installation and avoid scratching the ball surface with hard objects. Use soft tools and apply even pressure. If fixation is needed, use clamps or dedicated fixtures to prevent localized stress and deformation.
