Ball Valve Series

  • Trunnion Mounted API6D Ball Valve

    Trunnion Mounted API6D Ball Valve

    Trunnion ball valves have the obturator bounded by trunnion which prevents axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball, the contact between surfaces generates the valve sealing; trunnion standard construction ensure automatic cavity relief in case of overpressure in body cavity; these valves can be selected for a wide range of applications with no specific limits to all sizes and pressures.

  • Double Block and Bleed Ball Valve

    Double Block and Bleed Ball Valve

    DBB valve is a “single valve with two seating surfaces that, in the closed position, provides a seal against pressure from both ends of the valve, with a means of venting /beeding the cavity between the seating surfaces.

  • Fully Welded Pipeline Ball Valve

    Fully Welded Pipeline Ball Valve

    Since the seat of the API 6D fully welded ball valve is made up of a carbon teflon seal ring and a disc spring, it is adaptable to changes in pressure and temperature and will not produce any leakage in the marked pressure and temperature range.
    Fully welded ball valves are widely used in domestic steel mills, petroleum, chemical, gas, boiler, paper, textile, pharmaceutical, food, ship, water supply and drainage, energy, polysilicon, electricity and so on.

  • Multi-Port 3 Way Ball Valve T Port

    Multi-Port 3 Way Ball Valve T Port

    Two-way and three-way ball valves are the most common types of ball valves. Three-way ball valves are especially useful because they can be set up in ways that simplify the control of gas and fluid flow. For example, they can be used to divert the flow of oil from one tank to another.

  • Top Entry API Standard Ball Valve

    Top Entry API Standard Ball Valve

    Top entry trunnion mounted ball valves are widely used in petroleum and natural gas pipelines, as well as in oil extraction, oil refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food, and paper making equipment. The top entry trunnion mounted ball valve is easy and quick to disassemble on the pipeline, and the maintenance is convenient and fast. When the valve fails on the pipeline and needs to be repaired, it is not necessary to remove the valve from the pipeline. It is only necessary to remove the middle flange bolts and nuts, remove the bonnet and stem assembly from the valve body together, and then remove the ball and valve Block assembly. You can repair the ball and valve seat online. This maintenance saves time and minimizes losses in production.

  • Double Eccentric Semi Ball Valve

    Double Eccentric Semi Ball Valve

    Eccentric semi-ball valve and flange valve belong to the same type of valve, but the difference is that the closure member of eccentric semi-ball valve is a sphere and this sphere can rotate around the center line of the body to achieve the open and close movement. Ball valves are mainly used for cutting, distribution and changing the direction of the media flow in pipeline application.

  • Floating Forged Steel Ball Valve

    Floating Forged Steel Ball Valve

    Principle of the forged steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.
