We have a large inventory of HVAC float valves and float valve parts for heating & cooling applications.
The Function of Float Valves
Float valves are used for a variety of things! They are simple mechanical liquid-level controllers. A float will detect a change in elevation of the liquid-free surface and, therefore, open or close the valve accordingly. The float valve maintains the water level in the cold water header tank, which regulates the pressure of the hot water system.
A float valve that isn’t functioning properly can cause your cooling tower to overflow and not work properly. If the pressure of the water is greater than the buoyant force of the valve, it can cause the ball or pan float to be forced down. This will result in the cold water basin flooding.
At Commercial HVAC Parts, we offer float valve kits that are compatible with your BAC (Baltimore Air Coil), Marley (SPX), and Evapco (Reymsa) applications. We’ll make sure you get the correct one! We offer “long” and “short” dual-rod assembly valve kits with both pan floats and ball floats. Our valve kits will meet the dimensions required for your application and boast a long lifespan with little maintenance. To check out our available stock, click here.
To summarize, float valves maintain water levels within your cooling tower application. For more in-depth information on the science of float valves, check out the information here!
