trunnion mounted ball valve
1 Design Features: Anti blow-out stem, Antistatic device, Fire safe design API 607 Soft Seat or metal seat, Double block and bleed.
2 Reduce leakage:
The connective position of valve body and bonnet is double sealed by gasket and O-ring,on this base,such factors as fire, high temperature, shock and uneven opening or closing of the torque all can't induce external leakage.
3 Its special design minimizes its operating torque
4 Durable using. The forged trunnion ball valve can stand wear and tear. It 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.
5 The split seat design makes the valve seal more reliable and more convenient for maintenance
