    1. Gas Ball Valve DN15-DN1200
      The gas ball valve features high safety performance, good turn off performance, long service life and no maintenance. This kind of valve is a ball with holes. The ball rotates around the axis which is perpendicular to the channel in order to open and close the channel. The gas ball valve is mainly applied in channel or equipment opening and closing.
    1. Fully Welded Ball Valve DN15-DN1400
      The fully welded ball valve adopts double piston structure which can ensure that the valve can open normally with small torque. It adopts bidirectional double-layer seal, ensuring that the second seal can work normally after the failure of the first seal. This valve features high safety performance, good turn-off performance, long service life which can be up to 20 years and no maintenance;
    1. Metal Seated Ball Valve DN15-DN800
      The ball surface and sealing surface of the metal seated ball valve adopts cemented carbide for coating and grinding, so that the surface has high hardness and the valve has good sealing performance with no leakage, high temperature resistance and corrosion resistance. The valve can be repaired after long time service, thus greatly reducing use-cost for customers.
    1. Floating Ball Valve DN15-DN50
      This type of fully welded ball valve is floating type. It features small volume, simple structure, excellent shutoff performance, and long service life. Clients can use it for over 20 years without the need of maintenance. This ball valve is mainly applied in underground pipelines,fluid control system, among others.
    1. Floating Ball Valve DN65-DN150
      This type ball valve adopts round steel bar handle. We have designed it with low torque and easy operation. Plastic cover is valued on the handle for convenient manipulation and aging resistance. This valve is mainly applied in branch pipelines, building control and drainage system.
    1. Floating Ball Valve DN150-DN350
      DN150-DN350 series floating ball valves adopt worm wheel opening method for low torque and easy operation. They are mainly suitable for the shut-off control of underground pipelines, petroleum industry, gas storage facilities, and tunnel construction, etc.
    1. Flanged Floating Ball Valve DN15-DN150
      Fully welded flanged floating ball valves from series DN15 to DN150 utilize flange connecting method to make them compatible with other flange-connected products. The valve replacement process is rather convenient. These kinds of valves are suitable for pipeline branches, underground pipelines, gas delivery equipment, liquid storage device, tunnel construction, etc.
    1. Flanged Floating Ball Valve DN150-DN350
      With a flange connecting method, this type of flanged floating ball valve is compatible with other flange-connected products. It shows rather easy valve replacement. The ball valve is mainly applied in the shutoff and control systemunderground pipeline, pipeline branches, power station construction, district heating, onshore platform, offshore platform, etc.
    1. Full Bore Floating Ball Valve DN15-DN150
      DN15-DN150 series floating ball valve features good flow capacity, no hindrance, and excellent shut-off ability. It is mainly applied in pipeline branches, underground pipelines, shipbuilding, gas storage equipment, liquid delivery equipment, tunnel construction, etc.
    1. Full Bore Floating Ball Valve DN200-DN350
      With the adoption of worm wheel, DN150-DN350 series floating ball valves feature small torque, good flowing capacity, and no hindrance. They are mainly applied in underground pipelines, stream control system, fluid control system, gas control system, gas pipelines, gas storage equipment, etc.
    1. Extended Stem Floating Ball Valve DN15-DN150
      This type of floating valve adopts extended stem structure. Downhole operation is unnecessary since users can operate outside the well with some special tools. Small wells are optional to improve security and save on costs. This valve is mainly used for pipeline branches, building control, fluid control, pipeline construction, stream control system, etc.
    1. Trunnion Ball Valve DN100-DN350
      The piston-type fixed valve structure has endowed this kind of ball valve with superb capacity to resist pipe stress. The bi-directional dual-seal structure guarantees the excellent sealing effect of the valve. And the bi-directional quadruple sealing method commits a highly reliable sealing result. This valve is mainly applied in underground pipelines, shipbuilding, gas storage device, fluid control device, tunnel construction, etc.
    1. Extended Stem Floating Ball Valve DN150-DN350
      The extended stem structure for this floating ball valve makes the downhole operation unnecessary, improving the safety and cutting on costs dramatically. It is applied in shut-off control of pipeline branches, underground pipelines,fluid control equipment, power station construction, onshore platform, offshore platform, shipbuilding, etc.
    1. Extended Stem Trunnion Ball Valve DN350-DN1400
      Wosheng adopts extended stem for this ball valve. The stem height can be adjusted according to clients’ request. Since no downhole operation is needed, the security of operating the ball valve has been largely improved and the total cost is saved considerably.
    1. Trunnion Ball Valve DN350-DN1400
      For this kind of trunnion ball valve, Wosheng employs the piston-type fixed ball valve structure to enhance its resistance to pipe stress. The stem is designed with blow-out proof structure and replaceable stem sealing system.
    1. Filter Ball Valve DN65-DN1000
      Wosheng adopts floating ball structure for DN65-DN300 series valves and fixed ball structure for DN350-DN1000. The column-shaped mesh filter is set middle the flow path of the ball, serving to block those solid impurities. Users are advised to close the valve and open the cover to remove the dirt out after a certain time running of the pipeline.
