正文:
FORGED FLOATING BALL VALVESBall valve Size & Pressure : 150# DN25-DN100 / 300# DN25-DN100 / 600# DN25-DN1001.Forged ball valve featureWINDMILL forged ball valve,the forging material can ensure sufficient rigidity and strength under maximum rated operation pressure without inherent flaw of cast. Enough wall thikness of separate body and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient to bear the stress of pipe.The internal parts of valve are carefully designed and selected to ensure reliability under all kinds of work condition.2.Anti-fire safe designWhen the trunnion ball valve be used normally,its sealed by seat and ball surface,seat retainer sealed by O-ring and body,this is soft sealed and reliable sealing.When the seat and O-ring are burnt,the seat retainer and body will be sealed by expanded graphite.Thus act anti-fire safe purpose.3.Anti-static deviceIn order to prevent friction among ball,stem and PTFE that generates static
