Ball Check Valve

A non-return valve that uses a freely moving ball as the closing mechanism to prevent backflow. When the forward flow pressure is sufficient, the ball is lifted from the seat, allowing flow through the valve. When flow reverses, gravity and back pressure push the ball back onto the seat, sealing the valve. This simple and robust design provides reliable operation with minimal maintenance, making it ideal for slurry, wastewater, and viscous fluid systems.


    Benefits

    • Self-cleaning design: The ball rotates during operation, reducing seat wear and preventing clogging


    • Simple and durable: Minimal moving parts ensure long service life


    • Excellent for dirty or viscous media: Suitable for slurry, sewage, and chemical applications


    • Horizontal or vertical installation: Flexible mounting based on pipeline layout


    • Low maintenance: Easy access and cleaning, no external actuation needed


    • Quiet operation: Reduces water hammer and noise in the system
