Floating Ball Check Valve

Floating ball check valve is a valve that combines float liquid level control and check function. It senses the liquid level change through the float to achieve unidirectional flow of the medium and automatic opening and closing, and has the dual functions of liquid level regulation and backflow prevention. The core functions include:

Liquid level control: The float links the valve disc with the rise and fall of the liquid level to maintain the set water level;

Backflow protection: The valve disc automatically closes when the medium flows in the reverse direction to prevent backflow from damaging the equipment.

Structure and working principle
Core components
Float: usually made of stainless steel or fluorine-lined material, linked to the valve disc through a connecting rod; Valve disc: spherical or lifting design, the sealing surface is made of rubber or fluoroplastic to enhance corrosion resistance; Valve body: right-angle or vertical flow channel structure, suitable for DN15-DN300 pipelines.
Working principle
Forward flow: when the liquid level rises, the float floats up, and the valve disc opens to allow the medium to pass; Reverse static/backflow: when the liquid level drops or the medium flows in the opposite direction, the float drives the valve disc to close and block the backflow.

Advantages
‌Dual function integration‌: Liquid level control and check valve are integrated to reduce the number of pipeline components;
‌Strong corrosion resistance‌: Fluorine-lined/stainless steel material is suitable for corrosive media such as acid, alkali, and high salt;
‌Low maintenance cost‌: No complex transmission mechanism, only the sediment on the surface of the float needs to be cleaned regularly.
