Characterized Control Valves
The Characterized Control Valve combines the high close-off capabilities of a ball valve with a characterized disc that ensures a true equal percentage flow characteristic to achieve superior light load flow control.
Belimo’s unique Characterized Control ValveTM (CCV) is very different. A special characterizing disc inside the valve gives it an equal percentage characteristic which is comparable with that of a globe valve of the same nominal size. The flow (the Cv value) is reduced to the required value by a combination of the hole in the ball and the shaped aperture in the disc. The increase in flow as the valve is opened is very slow and controlled. This produces better part-load behavior and improved stability of control while also optimizing energy consumption.
