The 2-way and 3-way regulator ball valves combined with the 3-point actuators or proportional actuators of SINTESI series provide a motorized ball valve with equal-percentage regulating curve. In general, the heat exchange is described with a typically non-linear relationship between flow and exchanged heat. The use of the regulating ball valves with equal-percentage characteristic, thanks to special adjustment discs, allows the compensation of any non-linearity, obtaining a characteristic curve installed as shown below. It is easy to understand how the regulation, on a system with constant gain, is positively affected in terms of stability.
