Ball Valve

Full welded ball valve

Full Welded Ball Valve is an isolation valve. It adopts trunnion mounted ball, forged metal parts, fully welded body design. The forged metal ensures the quality of the body and trim. The fully welded bonnet ensures the strength and rigidity of the valve while eliminates the possibility of medium leakage. The double floating seats and bi-directional sealing design adopts unique two layer soft sealing and metal to metal sealing, the triple sealing structure ensures the reliable sealing performance with low torque and easy operation. This type ball valve is widely used on oil & gas pipeline and liquefied gas, coal gas, petrochemical, chemical, refinery, medicine, mining, etc
