When the one seat is damaged and the shut-off is not strict, the other side seat balance hole is used for the valve. The pressure inside the chamber is balanced, so that the spring compensation valve seat is in close contact with the valve ball to maintain the seal, and the two-way seat is completely sealed.
Then the investigation team of Yucheng Thermal Power Plant came to the production workshop and learned that our large-diameter welded ball valve is integrally forged by the side valve body. There is no fillet weld and it can cope with strong axial stress. It is used for direct-buried heating pipe network or underground pipe gallery with large axial stress, and has the same life as the pipeline. The design life is 30 years.
