  • Angle Globe Valve

    Angle Globe Valve

    Angle globe valve is mainly used to connect or cut off the medium in the pipeline. The valve opening and closing parts are plug shaped disc and sealing surface is flat or cone. The disc moves in a straight line along the center line of the fluid. The inlet and outlet channels of the globe valve are not in the same direction and form a 90°right Angle.
  • Insulated Jacketed Ball Valve

    Insulated Jacketed Ball Valve

    Insulated jacketed ball valve has the function of heat preservation and cold insulation. The nominal diameter is same as the pipe diameter. the medium is linear flow, small resistance, more suitable for easy solidification, high viscosity liquid medium. The valve is more suitable for liquid of linear flow, low resistance, easy solidification and high viscosity.
  • Double Eccentric Butterfly Valve

    Double Eccentric Butterfly Valve

    Double eccentric butterfly valve based on the single eccentric butterfly valve, the most widely used double eccentric butterfly valve is further improved. The structural feature is that the axis of the valve stem deviates from the center of the butterfly plate and the body. The butterfly valve seat can be separated from the butterfly valve seat quickly, which can reduce the unnecessary abrasion of the butterfly valve seat.

  • Cast Iron Globe Valve

    Cast Iron Globe Valve

    Cast Iron globe valve is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so Cast Iron The diameter of the valve stem of the globe valve should be large, otherwise the valve stem will bend up failure.
