Unlike standardized float balls, magnetic flap float balls often require customized dimensions and internal magnet configurations because different level measurement systems operate under different working conditions. This 50*247 Steel Float Ball for Magnetic Flap uses 316L stainless steel, an elliptical body design and high-temperature-resistant samarium cobalt magnets to provide stable operation in demanding level measurement environments.
The float ball is manufactured from stainless steel 316L according to the customer's drawing. The material provides corrosion resistance and is suitable for applications requiring reliable performance in demanding process environments.
The 50*247 Steel Float Ball for Magnetic Flap is designed according to the specified operating conditions. The float can be configured for high-temperature applications, with the customer's actual temperature and pressure requirements considered during production.
A samarium cobalt (SmCo) magnet is used instead of a conventional neodymium iron boron magnet. SmCo provides good magnetic stability and high-temperature performance, making it suitable for float balls used in elevated-temperature environments.
The internal magnet arrangement is not based on a conventional single circular magnet. For this project, six cylindrical magnets are evenly distributed along the inner tube according to the customer's magnetic force requirements. This configuration helps the float generate the magnetic response required to drive the external magnetic flap indication system.
The float ball adopts an elliptical structure with reinforcement ribs positioned at key stress-bearing areas. Compared with traditional designs featuring numerous ribs around the entire body, this structure reduces unnecessary external ribbing while maintaining the required structural support.
The optimized external surface reduces unnecessary structural features on the float ball. This can help the float move more smoothly in applications involving viscous or relatively high-viscosity media.

There is no single industry-standard design covering all magnetic flap float balls. The required dimensions, buoyancy, pressure resistance, magnet arrangement and material selection can vary depending on the level indicator, process medium and operating conditions.
For this reason, Sanlo produces the 50*247 Steel Float Ball for Magnetic Flap according to customer drawings and application requirements. Before production, key parameters such as dimensions, material, operating temperature, working pressure, medium density and required magnetic force can be reviewed to determine the appropriate float ball structure.
Customer drawings are used as the primary reference for dimensions and structural configuration. Where necessary, the internal magnet arrangement can also be adjusted according to the required magnetic response.
The internal structure can be designed around the magnetic force required by the external magnetic flap. For this 50 × 247 mm design, six cylindrical SmCo magnets are distributed along the inner tube to provide the required magnetic interaction.
Traditional magnetic flap float balls may use multiple external ribs to increase pressure resistance. The optimized design concentrates reinforcement on the main stress-bearing areas, helping maintain structural strength while creating a cleaner external profile.
The magnet material has a direct influence on the operating stability of a magnetic float ball. Neodymium iron boron provides very high magnetic performance but generally has lower temperature resistance, while ferrite offers lower cost but weaker magnetic performance. For high-temperature magnetic flap applications, samarium cobalt provides a useful combination of temperature resistance, oxidation resistance and magnetic stability.

The 50*247 Steel Float Ball for Magnetic Flap is designed for magnetic level indication systems where the float needs to move with the liquid level and transmit its position through magnetic coupling to an external indicator.
The float is used as the moving element inside a level measurement chamber. As the liquid level changes, the float moves accordingly and its internal magnets interact with the external magnetic flap mechanism.
With 316L stainless steel construction and SmCo magnets, the float can be considered for applications where elevated temperature places higher demands on material and magnet selection.
The reinforced structure can be customized for applications with specified pressure requirements, including working conditions requiring pressure resistance of 5 MPa or above.
The streamlined elliptical structure with localized reinforcement can be used in applications involving viscous media where excessive external ribs may affect float movement.
Sanlo focuses on customized float ball manufacturing rather than applying one fixed structure to every magnetic flap application. Each project can be evaluated according to the customer's drawing and actual working conditions.
Customers can provide drawings or technical requirements for the 50*247 Steel Float Ball for Magnetic Flap, including dimensions, material requirements, pressure, temperature, specific gravity, magnet strength and installation conditions.
