Full Diameter Worm Gear Full Welded Ball Valve
Full diameter worm gear welding ball valve flow channel adopts full flow structure. The valve has a floating ball structure, and the inclined elastic seal is pressed on top of the ball, even in the case of unstable pressure, the valve can be tight. The stem leak proof structure uses two "o" rings to allow the stem to turn freely and seal tightly. The product consists of a fully welded body and carbon reinforced Flon gaskets for long life in the presence of impurities and chemicals during frequent operation. Finely ground stainless steel ball can open and close freely for many years, reliable operation.
