Water installations, industrial plants, fire 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 stabilization of the medium 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 adapted to the requirements of a specific installation.

Float valve operating principle

Float valves are used to automatically regulate the level of the medium 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 buoyancy of the float. When the liquid level in the tank is low, the valve remains open, which allows the medium to flow in. The degree of opening of the float valve depends on the degree of opening of the main valve. When water enters the tank, its level rises and the float closes the valve, thus stopping the flow of the medium. It remains closed until the liquid level drops below the predetermined level, then the process is repeated.

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 oh   industrial : e.g. in the food processing industry, in the production of beverages, drinks, cosmetology and pharmacy as well as chemical synthesis plants;

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

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

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

  • rainwater tanks , where they close the inflow when a certain level is reached.

The variety of float valves allows you to choose a model that is tailored 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.
