Soft‑seat valves use PTFE or reinforced polymer for sealing – suitable for clean fluids below 200°C. Metal‑seat valves use hardened alloys (Stellite, carbide) to withstand high temperature (up to 600°C), high pressure, and abrasive or corrosive media. They offer longer cycle life and are fire‑safe.
Absolutely. We offer full OEM/ODM services: custom face‑to‑face, special flanges (ANSI, DIN, JIS), butt weld ends, and grooved connections. Our engineers will adapt the design to your piping system.
For standard sizes (1/2″ – 12″ Class 150/300), lead time is 2–4 weeks. Rush orders (up to 4″) can be shipped in 7–10 working days. Large quantities or high‑pressure classes require 4–6 weeks.
Yes. We support paid samples with full refund on the first bulk order. Sample cost: low, and we offer DHL/FedEx express. You can also request a free sample if the project is urgent.
Every valve undergoes hydrostatic shell and seat test, high‑pressure air test, and fire‑safe test (if required). We issue material certificates, NDT reports (X‑ray, PT, MT) upon request. Third‑party inspection (SGS/BV) is welcome at your cost.
Common terms: T/T (30% deposit, 70% against BL copy), L/C at sight, Western Union, and PayPal for samples. For repeat/long‑term customers, we can negotiate net‑30 or open account.
Send us your working temperature, pressure, media (viscosity, chemical composition), and required end connection. Our technical team will recommend the appropriate seat coating, body material, and trim. You can also use our online RFQ form: thriveonvalves.com/contact.
We ship via sea (FOB Tianjin/Shanghai) for full containers, air freight for small orders, or express (DHL/UPS) for samples. We handle all documentation and can arrange door‑to‑door delivery to your port or warehouse.
“We’ve been using Thriveon’s metal seat ball valves for three years in our steam distribution system. Zero failures, zero leaks. Their team helped us customize the seat coating for superheated steam at 550°C. Excellent value.”
“The cost savings compared to European suppliers are significant – around 40% – without any compromise on quality. The documentation and certificates are always complete. A reliable partner.”
“I was skeptical about importing valves from China, but Thriveon changed my mind. Their API 607 fire‑safe report was genuine. The valves passed our shutdown test with flying colors. We now stock their metal seat valves for all critical applications.”
“We needed high‑pressure (Class 600) ball valves with long neck for insulated lines. Thriveon delivered exactly to our spec in 5 weeks. The technical support from their engineers was outstanding.”
“We compared five suppliers, and Thriveon won on both price and expertise. The valve performance in our thermal oil system is flawless. We’ve placed three repeat orders already.”
Get your custom quotation within 12 hours. We offer free samples for qualified projects and a 100% money‑back guarantee if the valve doesn’t meet your performance specifications.
Limited‑time offer: Free expedited shipping for the first order (up to $500 value). Offer valid for the next 14 days.
