Seeko is one of the leading China Fully Welded Ball Valve manufacturers, welcome to inquiry Fully Welded Ball Valve from our factory.
FULLY WELDED BALL VALVE DESCRIPTION
The ball of trunnion mounted configuration is supported by bearing plates hold by the end adaptors. In such a way the pressure loads are transferred to the valve body granting a smooth rotation of the ball with low torque levels and reduced seat seal wear.
On SEEKO Trunnion Mounted Welded Body Ball Valves the potential leak paths are minimized making them suitable for buried installations and in general for gas transportation.
The weight and overall dimensions are optimized by applying forged or shaped design.
They are manufactured in a wide range of sizes and pressure classes from forgings.
