Eliminate valve failure downtime and excessive maintenance costs. Our lever operated butterfly valves deliver reliable quarter-turn flow control for industrial pipelines, backed by rigorous ISO 9001 & CE certification and a supply chain that ships to the USA in 25–35 days.
✓ Trusted by buyers in USA, Saudi Arabia, South Africa & Italy | 10,000+ valves shipped annually
Inferior sealing materials cause leakage after just 2,000–3,000 cycles. For a chemical plant, a single unplanned shutdown can cost $12,000–$25,000 per hour in lost production.
A cheap lever operated butterfly valve may save 20% upfront, but replacement parts, labor, and disposal fees push the total cost of ownership 37% higher within 18 months (based on 2024 industrial procurement data).
Many suppliers quote 15 days but deliver in 45+. Thriveon's factory in Hebei, China, ships 95% of orders within 25 days — confirmed by our 2025 logistics KPI report.
Valves that lack CE, ISO 9001, or API 609 certification can cause regulatory fines and safety incidents. We ensure every lever operated butterfly valve meets or exceeds these standards.
➡️ You need a partner who delivers certified quality, on-time delivery, and transparent pricing — not empty promises.
We produce butterfly valves, gate valves, globe valves, check valves, ball valves, strainers, and foot valves under one roof. This means consistent quality, faster lead times, and lower logistics costs for you.
Every lever operated butterfly valve is hydrostatically tested at 1.5× rated pressure. We hold ISO 9001:2015, CE (PED 2014/68/EU), and API 609 certifications. Pressure test reports are included with every shipment.
Need a custom lever length, special disc coating (nylon, PTFE, or epoxy), or unique stem material? Our engineering team has 10+ years of custom valve design experience. Send us your drawing, and we'll deliver the prototype in 15 days.
Our streamlined production line and dedicated export team ensure standard orders ship in 20–25 working days. Express delivery available for urgent projects. We ship via sea, air, or express (FedEx/DHL).

Used in a municipal water plant in Texas, USA — 200 valves (DN200, EPDM liner) have been operating for 18 months with zero leakage incidents. Customer reported 23% reduction in maintenance labor costs.
A chemical distributor in Saudi Arabia uses our PTFE-lined lever operated butterfly valves for aggressive media. Result: valve replacement frequency dropped from every 6 months to every 18 months — saving $4,700 per valve position annually.
A commercial contractor in South Africa installed 350 lug-type lever butterfly valves for a fire suppression system. All passed third-party pressure testing on first try. Project completed 2 weeks ahead of schedule thanks to on-time delivery.
Used in crude oil transfer lines in Italy — our ductile iron valves with FKM seats handle hydrocarbons reliably. Customer reported 97% uptime over 12 months of continuous operation.
A lever operated butterfly valve is a quarter-turn manual valve that uses a disc to regulate flow. The lever rotates the disc 90° from fully open to fully closed. It's ideal for on/off or throttling service in water, chemical, oil, and gas applications. The lever provides visual position indication and requires no external power source.
Pricing depends on size, material, and quantity. For example, a DN100 (4″) ductile iron wafer lever operated butterfly valve with EPDM liner starts at approximately $18–$32 per unit (FOB Tianjin) for standard orders. Custom materials (SS316, PTFE-lined) and OEM designs are quoted individually. Request a quote and we'll provide a detailed price list within 4 hours.
We accept T/T (bank wire transfer), L/C at sight, PayPal (for samples), and Western Union. For new customers, a 30% deposit with 70% balance against copy of shipping documents is standard. Long-term partners may qualify for open account terms (subject to credit approval).
Yes. We offer custom lever lengths, locking handles, gear-operated options, and wing nut handles. Our OEM/ODM team can also incorporate your logo, specific lever color, or safety-lock mechanism. Minimum order quantity for custom handles is typically 50 units, but we can discuss based on your project scale.
Every batch follows a 3-stage QC process:
Shipping costs vary by order weight and volume. To give you a ballpark: a 20GP container (approx. 1,000–1,200 pcs of DN100 valves) ships to Los Angeles or Houston for roughly $1,200–$2,000 (sea freight, as of Q2 2025). Standard delivery is 25–30 working days after deposit. Express shipping (FedEx/DHL) takes 5–7 days for sample orders.
Yes. We provide free samples (you pay shipping) for qualified buyers. Standard sample is 1–2 pcs of DN50–DN100 size. We can also customize the sample to your required material/seat. Sample lead time: 5–7 working days. Contact our sales team to arrange.
We offer 12-month warranty against manufacturing defects from the date of shipment. Our technical team is available via email, WhatsApp, and video call for installation guidance, trouble-shooting, and maintenance support. We also keep a spare parts inventory for rapid dispatch if needed.
