The water flow control in the finned coil is acieved through a 2-way modulating ball valve with equal
percentage flow control ensured by the integrated characterizing disc.
This type of valve offers the following series of benefits:
Equal percentage flow control.
No peaks initial flow.
Excellent stability control thanks to the integrated characterizing disc.
Excellent characteristic in partialisation.
Stability in control.
Maintenance free.
Self-cleaning.
CHARACTERISTICS OF THE 2-WAY BALL VALVE
Closing seal with leakage rate in Class A (EN 12266-1)
Maximum fluid pressure Ps=1600kPa
Maximum closing pressure (Close-off) ∆Ps=1400kPa
The rotative actuator is controlled by a signal 0 ... 10VDC from the microprocessor controller. The
actuator is equipped with an emergency button for manual operation and is maintenance-free.
