Product overview
Forged steel floating ball valve, forged material can ensure sufficient hardness and strength, and there are no internal defects under the maximum rated operating pressure. The valve is designed with a floating ball structure. The sufficient wall thickness determines the body and adapts to different high-strength bolt valve systems. The valve trim which is convenient for maintenance and sufficient to bear the pressure pipeline valve is carefully designed, and the working conditions with reliability under various working conditions are selected. It is widely used in polysilicon, coal chemical industry, petrochemical industry, petroleum and other fields.
