Slide Rolling Ball Check Valve

Essence: A valve that achieves one-way opening and closing by rolling a rolling ball along a slide, using the self weight of the ball or the pressure of the medium to block backflow.


Core features:

Rolling ball+slide structure: The ball freely rolls inside the guide rail, pushing it open when flowing forward, and quickly resetting and sealing when flowing backward;

Low flow resistance design: Full bore flow channel, suitable for high flow rates, particles or viscous media;

Wear resistance and high temperature resistance: Metal spheres (such as stainless steel) are suitable for high temperature or corrosive working conditions, with a long service life.

Typical applications: Pipeline systems that require wear resistance and backflow prevention in industries such as petroleum, chemical, and slurry transportation.

  • Energy conservation, environmental protection, and system protection
  • Flexible installation and wide applicability
  • Wear resistant and long-life materials
  • Low flow resistance and full channel optimization
  • Efficient sealing and silent closing design
Energy conservation, environmental protection, and system protection
  • 01
    Reduce water energy waste
    Low flow resistance design reduces pump load, increases energy efficiency by over 20%, and reduces annual water energy loss by thousands of tons;
  • 02
    Preventing water hammer hazards
    The rolling ball slow closing mechanism combined with sealing and noise reduction characteristics effectively eliminates water hammer impact and protects the pump body and pipeline system.
Flexible installation and wide applicability
  • 01
    Multi directional installation adaptation
    supports horizontal or vertical installation without directional restrictions, meeting complex pipeline layout requirements;
  • 02
    Wide temperature range and medium compatibility
    The working temperature range is 0-80 ℃, and it can be adapted to media such as cold water, hot water, industrial wastewater, and oil products.
Wear resistant and long-life materials
  • 01
    High strength material combination
    The rolling ball is made of 304 stainless steel or ceramic material, and the slide is treated for wear resistance, corrosion resistance, erosion resistance, and can withstand media containing impurities;
  • 02
    Maintenance free operation
    The slide guides the rolling ball to move, reducing friction loss, with a service life of up to one million opening and closing cycles, and reducing operation and maintenance costs by 60%.
Low flow resistance and full channel optimization
  • 01
    Full water flow channel design
    The valve body has no reduction in diameter, the flow cross-sectional area is consistent with the pipeline, the head loss is reduced by about 50% compared to traditional swing type, the flow rate is large and the resistance is small;
  • 02
    Suitable for high flow rate media
    The full bore structure is suitable for clean water, sewage, granular or viscous liquids, especially for high flow scenarios such as submersible sewage pumps.
Efficient sealing and silent closing design
  • 01
    Rubber rolling ball+slide structure
    The rolling ball wrapped in rubber is matched with an integrated slide. When closed, the rolling ball tightly adheres to the valve seat, achieving a leak free seal, and the soundproof closure avoids water hammer impact;
  • 02
    Spring assisted rapid locking
    Combining gravity and medium pressure, the rolling ball quickly resets when flowing in reverse, blocking the risk of backflow.
