The float valve sealing ring SFDN80 is a sealing component specially designed for mechanical float level controllers. It is a circular sealing element, usually made of elastic materials such as rubber or plastic, to adapt to the movement of the piston during the operation of the float valve and ensure effective sealing to prevent fluid leakage.

In float valves, the float valve sealing ring SFDN80 is used to withstand liquid pressure while maintaining the sealing performance of the valve in conjunction with the piston or float. When the liquid level in the fuel tank or other container rises, the float rises and the piston moves accordingly. The sealing ring must deform according to the movement of the piston to keep the valve closed and prevent excessive liquid from entering the container. On the contrary, when the liquid level drops, the float and sealing ring both descend, and the piston opens, allowing the liquid to flow out or replenish into the container.

The design of float valve sealing ring SFDN80 must be able to maintain their shape and sealing performance under different temperature and pressure conditions, while also being able to withstand chemical corrosion that may exist in the liquid. Therefore, the selected materials usually have good chemical resistance and certain temperature resistance.

When maintaining and replacing sealing rings, it is necessary to ensure that the size and shape of the sealing ring meet the design requirements of the float valve, as well as the perfect fit with the piston or float ball. Any improper installation may lead to leaks or other operational issues.

The float valve sealing ring SFDN80 of the float valve is one of the key components for the normal operation of the float valve, and its performance directly affects the control accuracy and system stability of the float valve. Therefore, selecting the appropriate sealing ring and ensuring its correct installation is crucial for ensuring the reliability and efficiency of the entire system.
