1) Ampio campo di portata regolato. La regolazione della portata viene effettuata per mezzo di un otturatore a farfalla a triplo eccentrico; 

bassa coppia di manovra, regolazione precisa ed estesa su tutta la corsa.

2) La forma dell’otturatore determina la caratteristica di regolazione lineare.
3) Sono integrate soluzioni per la protezione dei componenti interni e dell’attuatore da danni derivanti da eventuali colpi d’ariete.
4) Riduttore per comando manuale con lettura diretta della portata regolata e blocco in posizione.

1) Valve can regulate a wide flow rate range. The flow rate regulation is done by the mean of a triple offset butterfly valve that assure low operating

torque and accurate regulation.

2) The disc shape determines the linear regulation characteristic.
3) Design includes specific features to avoid damages to the internal component and the actuator in case of water hammers.
4) Gear box for manual actuation, with regulated flow rate reading and position lock.
