Baltimore Aircoil (BAC) RK0331M5 Make-Up Float Valve Kit

The Baltimore Air coil (BAC) RK0331M5 Make-Up Float Valve Kit is an essential part of the evaporative cooling towers because it is used to regulate water levels for HVAC systems. This kit generally contains a float valve which is a mechanical component that controls the flow of the water basin. When the water level decreases, the float goes down and this leads to the opening of the valve to allow more water in. This water level increases, the float rises and shuts the valve to avoid the water from overflowing.
