Eliminate fugitive emissions, reduce unplanned downtime, and secure reliable flow control — with ISO 9001-certified trunnion ball valves built for Oil & Gas, petrochemical, and power generation applications.
✅ 10+ years R&D experience | ✅ 15,000+ valves exported globally | ✅ Full OEM/ODM capability
Leaking stem seals and body joints cause expensive media loss, environmental fines, and safety hazards — especially in high-pressure gas services.
Standard floating ball valves fail under high differential pressure, leading to costly unscheduled maintenance and production stoppages.
Western-made trunnion valves carry high price tags and long delivery windows. Meanwhile, low-cost alternatives from unverified suppliers compromise quality and safety.
Many suppliers lack API 6D, ISO 15848, or CE/PED compliance, making it impossible to pass site acceptance tests or meet insurance requirements.
Slurry, sand-laden fluids, or high-velocity gas cause rapid seat erosion, leading to internal leakage and reduced valve life in 6–12 months.
Need special materials (duplex, Inconel), extended bonnets, cryogenic service, or actuator mounting? Off-the-shelf suppliers often cannot deliver tailored solutions.
Unlike standard floating ball valves, our trunnion ball valve design anchors the ball at both top and bottom, reducing operating torque, eliminating seat damage under high pressure, and providing bi-directional zero-leakage shut-off. Here's how we solve your pain points:
Meet API 6D requirements with a self-relieving seat that provides positive isolation on both upstream and downstream sides. Our valves are tested to zero leakage (Class VI per FCI 70-2) for fugitive emission control.
Choose from carbon steel (A216 WCB), stainless steel (CF8M, CF3M), duplex (F51/F53), or Inconel — all sourced from certified mills. Body and bonnet thickness exceed ASME B16.34 minimum requirements by 12% for added safety margin.
Our proprietary metal-seated + PTFE/PEEK insert design handles abrasive media, high temperature (up to 600°C), and high pressure (up to 2500 PSI) with extended cycle life — proven in slurry and steam services.
Certified to API 607 / ISO 10497 fire-safe testing, with anti-static devices ensuring electrical continuity. Our trunnion ball valves are approved for refineries, gas plants, and offshore platforms.
Delivered with ISO 5211 mounting pad for easy automation. We also supply custom actuator brackets, limit switches, solenoid valves, and positioners — a true single-source solution for your flow control system.
Our vertically integrated factory in Hebei, China, with over 50 CNC machines and a dedicated casting workshop, enables standard delivery of 25–40 days (vs. 60–90 days from European/US suppliers). Urgent orders shipped in 18 days.

"We replaced our previous European trunnion valves with Thriveon's API 6D units on a high-pressure gas pipeline. After 18 months, zero leakage and 22% lower torque — plus they saved us 37% on total procurement cost. Highly reliable."
"We needed 36" Class 1500 trunnion ball valves for an offshore platform with a tight 10-week delivery. Thriveon delivered in 8.5 weeks with full documentation, NACE compliance, and passed FAT with zero non-conformances. Exceptional service."
"Their metal-seated trunnion valves solved our chronic erosion problem in ash slurry service. Previous valves lasted 6 months; Thriveon's have been running for 14 months and still holding zero leakage. Maintenance cost reduced by 60%."
"Thriveon's team helped us design a custom cryogenic trunnion ball valve for LNG service with an extended bonnet and Class VI shut-off. The engineering support was outstanding, and the price was 40% below the nearest bid."
"We've been sourcing trunnion ball valves from Thriveon for over 5 years. Their quality is consistent, they always provide complete material traceability, and the after-sales support is immediate. A true long-term partner."
