Our manual butterfly valves are designed for industrial-grade performance across water treatment, HVAC, chemical processing, oil & gas, and general pipeline isolation. Here's what sets them apart:
We control every step of production in our Northern China facility – from ductile iron casting to precision machining and assembly. ISO 9001 processes ensure each valve meets rigorous pressure and leak-test standards before shipping.
Our engineering team has 10+ years of experience customizing valve dimensions, disc materials (CF8, CF8M, duplex), seat liners (EPDM, NBR, PTFE, Viton), and actuation mounting. You spec it, we build it.

Municipal plant in Saudi Arabia replaced aging gate valves with our DN400 manual butterfly valves (EPDM-lined). Result: 100% leak-free operation, 37% faster installation, and 50% cost savings over previous supplier.
Commercial complex in the US used 500+ wafer-style manual butterfly valves (DN50–DN200) for chilled water and hot water isolation. Delivered in 18 days – ahead of schedule. Zero defects reported.
Italian petrochemical plant sourced DN300 lug-style manual butterfly valves (WCB body, PTFE seat) for secondary pipeline isolation. Full EN 10204 3.1 certification provided. Valve performance exceeded expectations at 16 bar operating pressure.
A manual butterfly valve is a quarter-turn valve that uses a rotating disc to control flow. Operated by a lever, handwheel, or gearbox, it provides reliable on/off or throttling service in pipelines. It's ideal for large-diameter applications where fast operation and low pressure drop are required.
Wafer style fits between flanges and is cost-effective for dead-end or isolation service. Lug style has threaded inserts allowing one-side removal without system drain. Flanged style (ANSI/DIN) provides bolted connections for high-pressure or high-temperature systems. We offer all three to match your piping design.
Absolutely. All our manual butterfly valves are designed and tested to API 609, ASME B16.34, and AWWA C504. We regularly supply ASTM A216 WCB, A395 ductile iron, and A351 CF8/CF8M materials to US buyers. Full material certifications and PMIs are provided.
Standard lead time is 15–25 working days for sizes up to DN600. For larger diameters (DN700+) or custom materials, 25–35 days. Urgent orders can be expedited to 10–12 days. We ship via sea from Tianjin port or air freight if needed.
Yes. Our engineers have designed over 200 custom valve configurations. We can modify disc material, seat liner, stem length, gearbox type, and coating. Simply share your drawings or performance requirements and we'll provide a tailored solution and drawing for approval.
Each valve undergoes 100% shell and seat pressure testing per API 598. We also perform dimensional inspection, material verification, and visual examination. A detailed test certificate and inspection report accompanies every shipment. Third-party inspection (SGS, BV) can be arranged.
Our standard MOQ is 10 pieces per size. For sample orders or urgent replacements, we can accommodate lower quantities on a case-by-case basis. Contact us with your specific needs.
We offer a 24-month warranty against manufacturing defects. Our technical support team responds within 2 hours during business hours. We provide replacement parts and remote troubleshooting – no call centers, just direct engineer-to-engineer support.
"We switched to Thriveon for our manual butterfly valve supply after persistent issues with our previous vendor. The quality difference was immediate – perfect sealing, precise dimensions, and the paperwork was complete. We've ordered over 600 units across three projects. Highly reliable partner."
"Delivery speed was critical for our desalination plant project. Thriveon supplied DN700 manual butterfly valves in 22 days – faster than any European supplier could quote. The valves performed flawlessly during commissioning. Their engineering support was responsive and knowledgeable. Will definitely reorder."
"We distribute valves across Europe and had trouble finding a manual butterfly valve supplier that could match our quality demands at competitive pricing. Thriveon has been a solid partner for 3 years. Their CE certification and PED compliance documentation are always accurate. Customer satisfaction rate with their valves is 99.2%."
"We needed manual butterfly valves that could handle abrasive slurry in a remote mining site. Thriveon custom-designed a reinforced seat and Ni-hard disc for us. Two years in service and no failures. Their after-sales support via WhatsApp is incredibly responsive – even for urgent troubleshooting."
"We sourced 850 manual butterfly valves for a large hospital campus project. Thriveon's pricing saved us 41% compared to the next bid. Delivery was on time in 3 batches. Every valve was tagged, packed professionally, and the test reports were organized by PO. Made my job much easier. Highly recommend."
