The float valve is often referred to as a ball float. Float valves are lever-operated valves meant to regulate the level of liquids. Since floats are utilized in various industries and applications, the operation of float valves is entirely mechanical.
How does a float valve work?
Float valves open and close based on the liquid level that the float senses. The float could be a hollow ball made of metal or plastic. The float valve can regulate the main valve via a sub-valve. The sub valve would establish a water level in the tank; if the water level exceeded this level, the sub valve would close, and the main valve’s back pressure chamber would swiftly handle this pressure. Consequently, the float valve can regulate the water level in major industrial plants.
Applications of float valves
- Controlling the water level in open and closed tanks
- Condensate tanks
- The traditional toilet cistern (W.C.). It is a cyclical operation, but the ball-float valve controls the water level continuously
- Useful in a regular residential overhead tank
- No need for monitoring or regulating
- Once the required water level is attained, the flow of water will be halted to prevent overflow or overfilling
- No electrical power is necessary; this is affordable. Beneficial for tank level control in distant places where there is no electricity supply
