COMPACT INTERNAL MECHANISM

How the Valve Controls Water Flow

Inside the housing, the float responds to changes in water level. The connected lever and sealing components then open or close the inlet as needed.

1
Water Enters The threaded inlet connects to the incoming water line.
2
Float Responds The internal float moves as the surrounding water rises or falls.
3
Valve Adjusts Flow The internal lever controls the opening and closing action.
4
Water Reaches the Target Level The valve closes the inlet when the selected level is reached.
