BIFFI Electric Valve Actuator
BIFFI Electric Actuator
The ICON is user friendly with a large LCD display that gives customers up to 64 programmable functions to tailor the actuator to their process. All the electronics and set up buttons are non intrusive.
The modular design also allows for customers to upgrade units to modulating service or network protocols without having to replace actuators. Quick attachment to quarter turn gear operators allows the ICON to be utilized on both quarter turn and multi turn valves.
