Features & Benefits

The rubber ball of SC41 rolls up and down inside the body to open and shut the valve. When the pump starts, the medium under pressure pushes the rubber ball up, to allow medium passing through. When the pump stops, due to the pressure of backflow in the pipeline, the rubber ball is forced to roll to the end of the body, to shut the valve. The rubber ball is made of cast steel, with elastic rubber vulcanized to ensure the sealing and buffering effect.

  • A. Body

    The ball check valve is a check valve with multi-channel and multi-cone inverted fluid structure.

  • B. Ball

    It adopts hollow steel ball with rubber. The rubber with good elasticity can not only ensure sealing, but also reduce the damage to the pipeline system during valve closing.

  • C. Structure

    When the valve is opened, the conical body with holes can fix the steel ball, eliminating the pressure on the contact area between the rubber ball and the conical body. It is surface contact that reduces the hydraulic loss caused by the vibration of the rubber ball in the valve body.

  • D. Advantages

    Stable operation, good sealing performance, long service life, low resistance coefficient and good shock absorption effect. Saving energy and preventing water hammer. Its requirements for water quality are not strict.
