Ball Valve FAQs For Buyers And Engineers
Are you a professional manufacturer or a trading company?
AOGONG is a OEM & ODM ball valve manufacturer with over 30 years of production experience. We operate our own factory with full in-house CNC machining, precision assembly, and pressure testing capabilities. If you are evaluating an industrial ball valve supplier for an EPC project or long-term procurement, you are dealing with the source factory directly.
Can I place a sample order?
Yes. Sample orders are accepted, including mixed samples across different specifications, sizes, or materials. This is particularly useful for procurement qualification or engineering review before a bulk order. Please contact us with your required DN size, pressure class, material, and seat type and we will confirm availability and lead time.
What body materials do your ball valves use?
We manufacture ball valves in a wide range of materials to match your operating conditions:
- Carbon Steel: ASTM A105, ASTM A216 WCB
- Low Temperature Carbon Steel: ASTM A350 LF2 (down to –196°C)
- Stainless Steel: ASTM A182 F304 / F316; ASTM A351 CF8 / CF8M
- Duplex & Super Duplex Steel: ASTM A182 F51 / F53
- Alloy Steel: ASTM A217 WC6 / WC9 / C5 / C12A; ASTM A182 F5 / F11 / F22
- High-Performance Alloys: Inconel, Monel, Hastelloy, 904L, Alloy 20, Zirconium, Titanium
What media are your valves compatible with?
Our ball valves handle a broad range of process media, including:
- Water, steam, and gas systems.
- Crude oil and refined petroleum products.
- Corrosive or abrasive industrial fluids.
- Specialized applications like Coal Chemical, Polysilicon, LNG, and Refineries.
Please share your medium composition, temperature, and pressure parameters — we will recommend the optimal configuration.
What are the temperature and pressure ranges?
- Metal seated ball valves: –196°C to +880°C; pressure range PN2.5 to PN420
- Soft seated ball valves: –29°C to +200°C
Our high pressure and cryogenic valves are engineered for severe service where standard designs fail, fully compliant with API 6D, ASME, and EN standards.
Can you manufacture valves with our brand or logo?
Yes. We provide full OEM ball valve manufacturing service, including custom branding, logo marking, and private-label packaging. We also support custom valve designs to your drawings or specifications. Please contact our team to discuss your requirements and MOQ.
What about the lead time?
- Standard stock items: Ready for dispatch within 15 days
- Custom or engineered valves: Typically 4–10 weeks depending on complexity (e.g., Inconel, PN420, cryogenic).
For EPC project procurement or bulk orders, contact us early to schedule production and confirm delivery windows.
