At USA 3D Valve Group Co., we are a leading manufacturer of trunnion ball valves, supplying industries worldwide with durable, precision-engineered flow control solutions. Our trunnion-mounted ball valves are manufactured under strict quality standards, making them suitable for critical applications where safety, reliability, and efficiency cannot be compromised.
We understand that industrial buyers are looking for more than just low prices — they need valves that meet global compliance standards, reduce downtime, and perform consistently under harsh conditions. That’s why our trunnion ball valves are trusted by oil & gas companies, EPC contractors, chemical processors, and power plants across North America, Europe, the Middle East, and Asia.
Unlike floating ball valves, trunnion-mounted designs feature a mechanical anchoring of the ball at both ends, which significantly reduces torque and wear. This design ensures:
Stable performance under high pressure – capable of handling Class 150–2500 pressure ratings.
Extended service life – reduced seat deformation and leakage risk.
Lower operating torque – making them easier and safer for operators.
Tight shut-off capabilities – preventing leakage in pipelines carrying gas, oil, and other hazardous fluids.
For buyers in industries where pipeline integrity is mission-critical, trunnion ball valves offer the optimal balance of safety, durability, and cost efficiency.
We manufacture a complete range of API 6D-certified trunnion-mounted ball valves that meet the requirements of both onshore and offshore applications:
