Where is the ball float for the 413AF-5A high level shutoff valve located on an operating storage tank?

The ball float for the 413AF-5A high level shutoff valve is situated on the exterior side of the tank at the required shutoff height. This specific placement ensures accurate measurement and control of the liquid level in the tank. By being located outside, it can effectively monitor liquid levels without being influenced by the tank's internal turbulence or other variables that might affect readings, ensuring the high-level shutoff function operates reliably.

This design allows for the float to respond directly to the liquid's height and trigger the shutoff mechanism when the specified level is reached, thereby preventing overflow and potential hazards associated with overfilling a storage tank. The integration of this float system is essential for safety and operational efficiency in managing fluid levels.
