Eliminate valve seizure and fugitive emissions in your pipeline. Designed for oil & gas, chemical, and power plants — where downtime costs $50,000+/hour.
✅ ISO 9001:2015 CE/PED API 6D ATEX — Full traceability & material certification included.
A single valve seizure at 600 psi can halt your entire production line. Average cost: $12,000–$50,000 per hour in lost output.
Low-cost floating ball valves fail under thermal cycling. You end up replacing them every 6–8 months — 3× the total cost of a quality trunnion valve over 5 years.
US EPA Method 21 requires strict leakage control. Non-compliant valves can trigger fines up to $37,500/day under the Clean Air Act.
Lead times of 20–30 weeks from European suppliers? You can't afford to wait. Thriveon ships from stock in 15–25 days — with full US import compliance.
👉 You're not alone. 78% of plant engineers report valve reliability as their #1 maintenance concern. See how Thriveon solves this →
Unlike floating ball valves that rely on line pressure for sealing, our trunnion-mounted design uses a fixed shaft to absorb thrust. The result: zero stem blowout, 50% lower operating torque, and reliable bubble-tight shut-off even at 1,500 psi.
The ball is secured by lower and upper trunnions — not the seats. This eliminates ball shift under high pressure and ensures consistent sealing for 25+ years in demanding services.
Our standard design provides positive isolation from both upstream and downstream — critical for maintenance safety in refineries and chemical plants.
From -46°C to +250°C (with options to 450°C). Suitable for LNG, steam, and high-temperature thermal fluids — no seat deformation guaranteed.
Stem sealing system with live-loaded packing and optional bellows seal. Tested to ISO 15848-1 Class B — well below the EPA 100 ppm threshold.
We keep 500+ units in stock in sizes 2"–24". Custom trims (with Hastelloy, Inconel, or Duplex) ship in 30–45 days — 50% faster than industry average.

📌 All valves are 100% hydrostatically tested at 1.5× rated pressure. Full material traceability provided with every order.
Replaced floating ball valves on a crude oil transfer line (600 psi, 150°F). Result: Zero leakage after 18 months, valve torque reduced by 40%. Customer reordered 48 units.
Installed 12" Class 300 trunnion valves with Hastelloy trim for chlorine service. Eliminated quarterly seat replacements — saving $47,000/year in maintenance.
Supplied 24" Class 1500 steam isolation valves for a 2 GW combined cycle plant. Passed all API 607 fire-safe tests on first try. Plant availability improved to 99.7%.
In a trunnion-mounted design, the ball is mechanically held by top and bottom shafts. This isolates the seats from the ball's weight, allowing lower operating torque and bubble-tight sealing at high pressure (up to 1,500 psi+). Floating ball valves rely on line pressure to push the ball into the seat — they tend to leak under low pressure and wear faster in dirty service.
Selection depends on your maximum operating pressure and temperature. Use ASME B16.34 tables as a baseline. Our engineering team offers free sizing & selection — simply send us your line pressure, temperature, and media. We'll recommend the optimal class and seat material.
Absolutely. We manufacture flanged (RF, RTJ, FF), butt-weld (BW), socket-weld (SW), and threaded ends. All dimensions comply with ASME B16.5 / B16.47. We also offer NPT, API 5B, and specialty threads.

"We've been using Thriveon trunnion valves for 18 months across 3 pipeline projects. Zero leaks, zero failures, and they ship 3 weeks faster than any competitor. The documentation is always complete — our auditors are happy. I've recommended them to 2 other pipeline operators."
"I specified Thriveon for a challenging chlorine upgrade. The team customized the trim to Hastelloy C-276 in 4 weeks — other suppliers quoted 16 weeks. The valve has been in service for 14 months with no measurable leakage. Exceptional quality for the price."
"We bought 24 Class 1500 trunnion valves for our superheated steam loop. Passed all fire-safe and cryogenic tests on the first go. Their engineer visited our site for commissioning — very professional. We're now a standard user across all 4 plants."
"Thriveon has been a reliable partner for our Middle East projects. On-time delivery rate: 98.5% over 3 years. Their pricing is 30–40% below European equivalents with equal or better quality. The CIF Dubai terms make logistics seamless. Highly recommended."
"I was skeptical about buying valves from China. But Thriveon's team sent full NACE paperwork, material certs, and a 3D model before shipment. Installation was plug-and-play. After 8 months in sour gas service — no corrosion, no leaks. I'm a believer."
Stop overpaying for slow, inconsistent suppliers. Get a custom trunnion valve quote in 24 hours — with full technical specs, CAD drawing, and a delivery schedule you can rely on.
