The QLF-450F indicator transfer is used in Hale QLF and QD manual transfer valves. These valves are used to switch between two sources of water, such as a pump and a tank. The indicator transfer helps the operator to see which source the valve is currently set to.
To transfer the indicator, simply move the lever on the transfer valve. The indicator will move along the spiral track to show the new position of the valve. It is important to make sure that the indicator is fully engaged in the new position before operating the valve.
If the QLF-450F indicator transfer becomes damaged or worn, it should be replaced immediately. A damaged indicator may not show the correct position of the valve, which could lead to operational problems or even safety hazards.
