Balls and accessories
The spheres are an integral part of our valves
Floats and accessories are coherently matched to each valve in order to guarantee their best and most correct functioning. ST has always produced plastic floats which, depending on the size of the valve and the operating lever used, have different anchoring systems such as the threaded brass inserts for round rods or the sliding attachment for flat rods.
The plastic balls are made of PEHD5502 high density polyethylene and are produced using blow molding machines. Furthermore, depending on the model, they are sealed by means of ultrasound or with the insertion of the previously heated brass threaded insert.
The plastics processing department has extrusion-blow molding and injection machines with an annual capacity of 800,000 plastic spheres
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.
