Designed for high pressure and large diameter applications, our cast trunnion ball valve offers superior strength, safety, and resistance to harsh environments.
The unique design minimizes valve seat pressure, ensuring long-lasting, stable sealing with low torque operation.
With two valve seats for bidirectional flow, the valve offers flexible installation and wider application versatility.
Supported by upper and lower bearings, the ball reduces friction for smooth, effortless operation.
XINTAI Valve’s trunnion-mounted ball valves feature Single Piston Effect (SPE) seats, which allow pressure relief on the upstream side while maintaining a secure seal downstream.
Creating an electrical connection between the ball, stem, and body. This prevents static buildup, reducing the risk of sparks in flammable environments such as petrochemical plants.
The blowout-proof stem design ensures the stem remains secured even under extreme pressure. This added safety feature prevents accidents, enhancing both operator protection and long-term valve performance.
