Ametek Model NL310WJ air volume control for deep well operation

Ametek Model NL310WJ low lead air volume control for deep well operation. Spec# 148540ANL

Ametek U.S. Gauge air volume controls are designed to maintain the proper ratio of air to water in hydropneumatic tank systems.

The NL310WJ is designed for deep well systems where some amount of air is pumped into the tank by the well pump along with the water. When there is an excess of air and the water level is low, the float opens the main valve of the control, permitting air to be vented to a chamber within the control. This chamber contains an adjustable pressure relief valve which exhausts the excess air to the atmosphere, providing the pressure in the tank is higher than the relief valve setting. As the float rises with the increase in water level the main valve closes, trapping the remaining volume of air in the tank. The optimum relationship between the volume of air and water in the tank is thus maintained.

U.S. Gauge low lead air volume controls adhere to the “Reduction of Lead in Drinking Water Act”.
