Welded ball valve

Since the valve seat is composed of carbonized Teflon sealing ring and disc spring, it has strong adaptability to changes in pressure and temperature, and will not produce any leakage within the marked pressure and temperature range. A steel ball and a spring are separately installed between the valve stem and the ball body and the valve stem and the stuffing box, which can maintain the conductivity of all parts of the valve and the valve body, allowing current to pass through the area and releasing static electricity. Not only avoid fires, but also avoid corrosion, and complete temporary interception for timely maintenance.
