Ball Type Check Valve

‌Ball check valve‌ is an automatic valve with a ball as the opening and closing element. It drives the ball to move through fluid pressure to achieve one-way flow control of the medium and prevent backflow. Its core functions include:

‌One-way cutoff‌: The ball opens when flowing forward and automatically closes when flowing backward to block the backflow of the medium;
‌Protection system‌: Reduce the water hammer effect to avoid pump reversal or pipeline damage;
‌Adapt to complex media‌: It can handle fluids containing solid particles and high viscosity (such as sewage and slurry).

Core structure and components
‌Valve body and ball‌
‌Valve body material‌: Stainless steel, ductile iron, PVC, etc., suitable for different pressures (Class 150~300) and corrosive environments;
‌Ball design‌: Mostly rubber-coated metal balls or wear-resistant alloy balls, with both sealing and impact resistance.
‌Sealing system‌
Soft seal (rubber, polyurethane) or metal seal, leakage ≤0.1% of the diameter;
Streamlined flow channel design to reduce fluid resistance.
