Track type steel ball valve is suitable for petrochemical, liquefied petroleum gas storage, oil refineries, natural gas, the compressor system, oil and gas pipeline, light industry, textile and other industries.
Product features:
■ open and close without friction. To solve the traditional valve sealing surface due to friction between the impact of sealing problems
A jacket type structure. Can be directly online inspection and repair of the valve installed in the pipeline. Can effectively reduce the device for parking, reduce production cost
■ single seat design. Remove the valve in the cavity medium affected by abnormal use boost security problems
■ low torque design. Special structural design of the stem, just with a little hand wheel can easily open and close the valve
■ wedge-shaped seal structure. The valve stem is provided by the mechanical force, the ball wedge pressure to the valve seat seal. The influence of the valve sealing performance is not affected by changes in pipeline pressure, the sealing performance under various conditions have a reliable guarantee
■ surface self-cleaning sealing structure. When the ball body tilt away from the valve seat, fluid in the pipeline along the sealing surface of the sphere into 360 ° evenly through. Not only eliminates the high speed fluid on the seat of local scour, also washed away the accumulation on the sealing surface, reach the self-cleaning purpose"
