TongBall Trunnion valve balls provides stable and leak-free control for high-pressure and high-integrity working conditions. The integrated support shaft ensures stability, and precise machining ensures the alignment of the ear-axis hole and the ball passage. Advanced surface treatment enhances wear resistance and anti-adhesion capabilities, reduces valve seat torque, and is suitable for natural gas, crude oil, refined oil, and corrosive fluids. The working temperature depends on the valve body/valve seat material.
