Important note:

For installation and operation, please pay attention to the instructions for floater valves of Navid Kariz Dostanan company.

Mechanism and how it works:

A-Floating valves 0 floater 9 hydraulic model (with pilot) of Navid Kariz Dostan company are designed in such a way that by adjusting the control circuit pilot outside the valve, if the water level of the tank rises to the desired level, under any working pressure of the valve, the water flow will be cut off. he does.

B- The mechanical model floater valve of Navid Kariz Dostan company is designed so that it can be directly operated by the lever and the arm connected to the float when the water level of the tank rises to the desired level, at low pressures and up to 5 times the water flow of the valve. cuts off
