Water installations, industrial plants, fire protection tanks - these are just some of the examples of the use of tanks for water or other liquids. In many cases, the key aspect of their operation is the automation of the filling process and the stabilization of the factor level. This function is performed by float valves . In the new entry, we describe the principle of their operation and explain how to choose a model tailored to the requirements of a specific installation.

Principle of operation of the float valve

Float valves are used to automatically regulate the medium level in the tank. They consist of three main elements:

  • connection module with seal;

  • arm;

  • float.

The operation of the float valve is based on the displacement of the float. When the liquid level in the tank is low, the valve remains open, allowing refrigerant to flow. The opening degree of the float valve depends on the opening degree of the main valve. When water fills the tank, its level rises and the float closes the valve, thereby stopping the flow of the medium. It remains closed until the liquid level drops below the set level. The process is then carried out again.

The simple principle of operation of float valves and their effectiveness in automating the regulation of liquid levels in tanks make them widely used in various sectors of the economy. They are most often used in:

  • installation   industrial : e.g. in the food processing industry, in the production of beverages, in cosmetology and pharmacy , and in chemical synthesis plants;

  • public facilities   such as swimming pools, fountains and ponds in public parks or gardens;

  • installation   fire protection : they are an important element, ensuring a constant water level in the fire protection tank and enabling immediate activation of the fire extinguishing system in the event of a fire;

  • installation   water supply systems , in which they regulate the water level in reservoirs supplying the network and ensure uninterrupted access to water for users;

  • rainwater tanks , where they close the flow when the appropriate level is reached.

The diversity of float valves allows you to select a model adapted to the specific needs of a given application. Individual valves may differ, for example, in terms of resistance to aggressive factors, tightness class or required frequency of service work.
