Eliminate reverse flow, protect your pumps and compressors with our precision-engineered one way butterfly valve. Designed for water treatment, HVAC, and chemical processing — ISO 9001 certified with 24/7 technical support for procurement managers and plant engineers.
Sudden valve closure creates pressure surges up to 10x of normal, cracking pipes and damaging expensive pumps. “We lost $47,000 in pump repairs last year alone.”
Backflow in chemical lines can contaminate entire batches. 1 incident can cost $80,000+ in product loss and cleanup.
Standard swing check valves fail unpredictably. Average 6.2 hours of downtime per failure — at $1,500/hour, that's $9,300 per event.
Stocking multiple valve types for different pressures adds SKU complexity. 30% of warehousing costs tied to valve inventory.
Poor sealing on standard valves leads to leakage. EPA fines up to $37,500/day for non-compliant emissions.
Long lead times from unvetted suppliers cause project delays. 40% of buyers report quality inconsistencies from Asian suppliers.
🔍 You're not alone. 73% of plant engineers tell us these issues keep them up at night.
Unlike traditional swing check or lift check valves, our patented wafer-style one way butterfly valve combines compact design, quarter-turn speed, and absolute backflow prevention in a single, cost-effective solution.
Dual-offset disc geometry with PTFE seat ensures bubble-tight shut-off per API 598. Tested to 1.1x rated pressure — no fugitive emissions.
Closes in less than 1 second when flow reverses — prevents water hammer before it starts. Ideal for automated systems with pneumatic or electric actuators.
Integrated spring-assisted disc returns to closed position instantly on flow stoppage. No external power needed for fail-safe operation.
Fits between ANSI B16.5 flanges — installs in 15 minutes. Reduces pipe stress and eliminates need for additional supports. Saves $200-400 per installation.
Available in WCB, CF8, CF8M, Duplex and Super Duplex. Pressure ratings from PN10 to PN40 (Class 150 to Class 300).
Custom trim materials, coatings (PTFE, Nylon, Epoxy), and actuator mounting. Prototype in 7 days — perfect for specialized chemical and marine applications.

📌 All valves are 100% hydrostatically tested before shipment. Test certificates included with every order.
A standard butterfly valve is designed for bidirectional flow control and shut-off. A one way butterfly valve (also called a butterfly check valve) automatically closes when flow reverses, preventing backflow. It combines the compact wafer body of a butterfly valve with the check function of a non-return valve — saving space, weight, and cost compared to using a separate check valve.
For standard sizes (DN50-DN300) in WCB or CF8M with PTFE seat, lead time is 7-12 working days. For custom materials or actuator mounting, 15-20 working days. We offer express production in 5 days for urgent orders with a 15% surcharge. Air freight or sea freight options available.
Yes, we offer 1-2 free samples for qualified buyers. You pay only the shipping cost (approx. $60-120 depending on size and destination). Samples are fully tested and come with a test certificate. Contact us with your DN size and pressure requirement.
We accept T/T (bank wire), L/C (irrevocable), and Western Union. For first-time buyers, we typically require 30% deposit, 70% before shipment. For established customers with good history, negotiable terms including DP and open account (upon credit approval).
Simply provide your flange standard (ANSI B16.5, DIN EN 1092-1, JIS, etc.) and nominal pipe size. Our wafer-style design fits between standard flanges without modification. We also provide free flange dimension check — just send a photo or drawing of your flange.
Absolutely. Our team of 6 senior engineers provides free remote technical support via WhatsApp, email, or video call. We offer installation manuals in English and can arrange on-site commissioning for large projects (travel expenses apply). Spare parts are available for all models.
There is no catch. Our cost advantage comes from vertical integration — we cast, machine, assemble, and test in-house at our Hebei factory. We pass on 30-50% savings compared to Western brands while maintaining ISO 9001 quality. Over 5,000 satisfied international customers can confirm: low price does not mean low quality. We also offer a 100% money-back guarantee if the product does not meet spec.
We ship via sea freight (FOB Tianjin or CIF to your port) and air freight (DDP option available). For USA, sea freight takes 25-35 days; air freight 5-7 days. For Middle East, sea freight 15-20 days. We also offer incoterms: FOB, CIF, DAP, DDP depending on your preference.

Ningjin Thriveon Valve Co., Ltd. — South of Huanmadian Village Town, Ningjin County, Xingtai, Hebei Province, China. Established 2008. Trusted by 2,100+ buyers in 35 countries.
“We installed 50 units of the PN16 one way butterfly valve in our cooling water system. Zero backflow issues in 14 months. The PTFE seat holds up perfectly with our treated wastewater. I've recommended Thriveon to two other plants in my network.”
“I was skeptical about buying valves from China directly. Thriveon changed my mind. The one way butterfly valve arrived in perfect condition, dimensions matched my ANSI flanges exactly, and the test pressure held at 1.5x with zero leakage. Their engineer Jason answered my technical questions at 10pm his time. Impressive.”
“Thriveon's one way butterfly valve is now our standard spec for all new HVAC projects. It's lighter than our previous check valve, easier to install, and the price is 35% lower. Over 600 units installed across 9 projects — zero field failures.”
“We needed a fast solution for backflow on our offshore platform. Thriveon's team designed a custom duplex one way butterfly valve with super duplex disc — delivered in 12 days. The quality is on par with our previous European supplier at half the cost. Will definitely order again.”
“We ordered 80 units of the electric actuated one way butterfly valve for our automated irrigation system. Integration was seamless, the actuator mounting bracket matched exactly. The customer service team followed up proactively to ensure everything worked. That's rare with overseas suppliers.”
