PVC Ball — Material Specifications, Engineering Data & OEM Supply
Produced at our Gujarat manufacturing works, PVC Ball offers superior sealing and wear resistance for precision valve balls. Combines virgin and reinforced PVC grades with precision compression moulding and 100% batch quality inspection for OEM applications.
Where PVC Ball is used
Sealing and flow-control element in ball valves and pump check seats, where sphericity and surface finish decide shutoff tightness and operating torque.
Selected for cold aqueous and mild chemical service where low cost outweighs temperature capability.
Supplied to drawing across the published range — Diameter
5mm to 310mm — industry-leading PVC Ball size range; Material: Rigid PVC (Polyvinyl Chloride) — with dimensional and material reports on request.

Manufacturing process
The manufacturing process for PVC Ball utilizes precision cold preforming of PVC followed by oven sintering. Automated hydraulic press cycles ensure consistent green compact density, which prevents localized voids and ensures uniform thermal expansion behavior during finish machining passes.
Material selection notes
Engineered from high-purity PVC, this component resists virtually all industrial acids, alkalis, and aggressive organic solvents. The non-stick, self-lubricating surface minimizes drag and prevents material buildup in fluid handling systems. Compressive deformation under load is optimized through tailored filler grades based on service pressure.
How to specify your order
To configure PVC Ball for your application, submit component dimensions, operating PV factors, and delivery port requirements. Our engineering team prepares complete technical evaluations and formal quotations within 24 hours.
Quality checks and inspection
Testing procedures for PVC Ball include optical comparator profile inspection, hydrostatic pressure holding tests on seal components, and material hardness checks (Shore D) to verify full sintering cure.
Ordering and export documentation
Domestic PVC Ball orders ship with GST invoice and e-way bill where applicable. Export orders include commercial invoice, packing list, and certificate of origin from our IEC-registered works. Recurring supply schedules supported with fixed drawing revision and lot numbering for plant stores Contact info@hemsun.com or sales@hemsun.com with your balls specification.
Export packing and lead time
Export logistics for PVC Ball cover global delivery via air freight or ocean container through Mundra and Nhava Sheva ports. Products are packed with protective foam wrapping and moisture-barrier film inside export-grade wooden crates, accompanied by certified commercial invoices and Certificates of Origin.
Storage and handling
Handling and assembly guidelines for PVC Ball: Components should be kept in protective polybags until final assembly. Use clean, rounded assembly mandrels when installing over shaft threads to prevent surface scratches or edge nicking.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Diameter and sphericity are verified on calibrated gauges and the achieved grade is recorded on the inspection report; sintered density is checked per ASTM D792. A mill test certificate ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
Frequently Asked Questions
What is the largest PVC Ball you manufacture?
We manufacture rigid PVC Balls up to 310mm diameter. Large PVC Balls serve large-bore water treatment check valves and chemical plant piping check valves.
What chemicals are PVC Balls resistant to?
Rigid PVC Balls resist inorganic acids (hydrochloric, sulfuric, phosphoric), alkalis, chlorine, brine solutions, and most inorganic chemicals. Not recommended for THF, cyclohexanone, and concentrated sulfuric acid — use PTFE or PVDF Balls for aggressive solvent or concentrated acid service.
Are PVC Balls flame retardant?
Yes. Rigid PVC Balls are inherently flame retardant — self-extinguishing per UL94 V-0. This makes them suitable for chemical plant and water treatment applications where flame retardancy is a requirement.
