Product Description

At its core, a float needle valve operates on a simple yet ingenious principle. It consists of a hollow needle attached to a buoyant float. As the liquid level rises or falls, the float moves correspondingly, adjusting the position of the needle within the valve seat. This movement regulates the flow of fluid, either allowing it to pass through or shutting it off entirely.

Mechanism and Working Principle

The functionality of a float needle valve hinges on the balance between buoyancy and gravitational forces acting on the float. When the liquid level rises, buoyancy lifts the float, causing the needle to retract from the valve seat, thereby allowing fluid to flow. Conversely, as the liquid level decreases, gravity pulls the float downward, pushing the needle into the valve seat to stop the flow.
