Water Level Control

FL Water-Level Control valve - Differential Type

Mounted on the tank / reservoir inlet, below or above the water level. Closes when the water level rises to the float location, preventing overflow, and opens when the water level drops.

FL

FLDI1 and FLDI2 Water-Level Control valve- Differential Type

Mounted on the tank / reservoir inlet, below or above the water level. It closes when the water rises to the requested maximal level, and opens when the water level drops to a preset minimal point. The level difference is adjustable.

FLDI

FLEL Electrically- Activated Level Control valve.

Mounted on the tank, / reservoir inlet, below or above the requested water level. Activated by an electric float pilot located in the tank / reservoir. It closes when the water rises to the requested maximal level, and opens fully when the water level drops to the preset minimal point. The differential between the water levels is adjustable.

FLEL

AL Altitude Control valve.

Mounted on the inlet of the tank / reservoir, below the water level. The valve is activated by the hydrostatic pressure of the water level. It closes when the water rises to the requested maximal level, and opens fully when the water level drops to the preset minimal point. The differential between the water levels is adjustable.

AL / PR, FLDI1 / PR, FLDI2 / PR Combination of Water Level and Flow Rate Control.

Mounted on the tank / reservoir inlet. It limits the flow into the tank, and maintains the preset maximal and minimal water levels.
 

AL / PS, FLDI1 / PS, FLDI2 / PS Combination of Water Level and Back-Pressure Control

Mounted on the tank / reservoir inlet. It maintains the pressure in the supply network and the preset maximal and minimal water levels.
