The fields of application of float valves
Each float valve has different characteristics to adapt and provide a specific service to each application sector.
The industrial sector has floats suitable for regulating the flow of water or other liquids inside civil and industrial tanks and basins, even of considerable size.
In agriculture ST products are used inside tanks for irrigation or for storage of fertilizers and other liquids in tanks. The valves used in farms for the operation of automatic drinkers for animals belong to the same sector.
The plumbing sector includes all types of float valves for toilet cisterns.
Balls and accessories are coherently matched to each tap to guarantee the best and correct functioning.
