“We reduced our valve-related downtime by 47% after switching to Thriveon.” – Technical Director, US HVAC Contractor
Our three way bypass valves are cast in ductile iron or stainless steel (CF8/CF8M) with PTFE or metal seats, ensuring zero leakage at pressures up to 25 bar. Ideal for bypass, mixing, and diverting applications.
Need specific flange drilling, stem extensions, or custom markings? Our in-house engineering team delivers tailored designs with a turnaround as fast as 15 days for prototypes.
Shipped via air or sea from our factory in Hebei, China – typical order fulfillment in 25–35 days. We manage all export documentation, including FCL/LCL consolidation to reduce your freight costs.
Every valve is tested per API 598. We hold ISO 9001, CE, and RoHS compliance. Third-party inspections (SGS, BV) are welcome at no extra charge.
Direct factory pricing eliminates middlemen. Typical savings of 20–35% compared to European or American brands, with identical or better performance.
Our senior engineers (10+ years experience) provide CAD drawings, torque calculations, and installation guidance within 2 hours of your inquiry.

Our three way bypass valve is widely used in boiler bypass systems, coil protection, zone mixing, and chemical injection lines.
“Excellent quality, on-time delivery” – We have been using Thriveon three way bypass valves for two years. They replaced a well-known Italian brand. No issues, perfect sealing, and the price is unbeatable. The technical support is very responsive. Our engineers love the ease of installation.
— Robert K., Senior Mechanical Engineer, Chicago HVAC Systems, USA
“Customization made easy” – Needed a special three way bypass valve with NPT threads and a stainless steel body for a water treatment plant. Thriveon produced 150 units within 25 days, including custom engraving. Communication was smooth, and the valves passed our 2,000 psi test with zero leaks.
— Maria T., Procurement Manager, AquaPure Inc., Florida, USA
“Saved 35% compared to our previous supplier” – I run a medium-sized industrial valve distributor in Texas. Thriveon’s pricing allowed us to win three new contracts. Their quality control is excellent – less than 0.5% defect rate. Highly recommend for US buyers seeking a reliable China valve manufacturer.
— David L., Owner, Lone Star Valve & Supply, USA
“Outstanding after-sales service” – One valve had a minor actuator mount misalignment due to our custom bracket. Thriveon shipped a replacement part via DHL within 3 days – no questions asked. That kind of support is rare from an overseas supplier. We will continue ordering.
— Alan S., Plant Engineer, PetroChem Ltd., South Africa
“Very good value for money” – The three way valves work perfectly for our HVAC bypass applications. The only minor suggestion: include a torque chart in the packing. But overall, satisfied customer. Will buy again.
— James R., Facility Manager, University of Michigan, USA
