           It is reported that most petroleum production countries make great use of long pipeline to transport different resource such as oil or gas. According to statistics, the total length for the pipeline used for transporting oil and gas has been over 2.6 millions kilometers. As the pipeline used for long transportation is very long and will pass through harsh places such as desert, forest, river, mountain, marsh and so on, the demand for long pipeline ball valve is higher than the common one to ensure the safety, sealability and strength.

            Valves are needed to regulate the flow of some liquid or air. Actuated ball valve is one of the types which has a spherical disk in it and the disk has a hole in it. When the hole is aligned with the rest of the hose or pipe, or open, it allows the liquid or air to flow through. When the hole isn't lined up with the pipe, or closed, there is no flow.

            1. One-piece body, there is no problem in the connection of body and yoke, which effectively improve the valve’s concentricity, allowing reliable connection of stem and ball and stable force in the process of open and close is uniform.

            Top entry eccentric half ball valve use that eccentric body, eccentric ball, seat and stem self-centering when make the rotary motion in common path and it is tighter during the close process and then completely achieve good sealing purpose. The valve seat completely break away the ball which eliminates the wear of sealing ring and overcome traditional problem of the wear among the seat, ball and sealing face. Nonmetal elastic material is embedded in metal seat and the metal surface of seat is well protected. Our products are especially suitable for medium of steel, aluminium, fiber, micro solid particles, paper and pulp, coal dust, liquefied petroleum gas, etc.

          Top entry ball valve is widely used in oil and natural gas pipeline, and oil extraction, oil refining and petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food and paper, etc. Top entry ball valve can be removed easily and quickly from the pipeline and is convenient to maintain. When the valve in the pipeline needs to be repaired, it’s no need to remove valve from the line, just pulling down the flange bolts and nuts, removing the bonnet and stem assembling unit from the body and the ball and seat assembling unit. Then we can repair the ball and seat online. The maintenance save time and reduce the loss to the least.

            1. Blow-out proof stem: In order to prevent the stem from flying off, resulting in abnormal rising of the inner pressure of valve, the shoulder is fixed at the lower part of the stem. Moreover, for the purpose of  preventing leakage resulting from burnout of packing set of the stem in a fire, thrust bearing is set at the contact position of the shoulder at lower part of the stem and valve body. And an inverse seal seat is formed which will prevent leakage and avoid accident.
