Electric Actuator
Introduction
The 480 series CENTORK electric actuator is covering the need of smaltorque quarter-turn actuators to complete the Centork electric actuators rangeCentork is presenting a range of actuators specifically designed for quarter-turnapplications (Butterfly, Ball, Plug valves and dampers) in industrial applicationswith the same quality and reliability of every Centork product and the nextcharacteristics:
Gearing:
With a double worm gear that guarantees the self locking and theaccuracy of the valve position and a low noise function. EP grease lubrication.maintenance free.
High enclosure protection:
The 480 series actuators are supplied with IP67enclosure protection, IP68 being an option. The 48A series are explosion-proofEexd IlBT4 certified.
High corrosion protection:
Epoxy powder coating as standard. OptionallyP1 and P2 protection classes for extreme conditions. All extemal screws aremade of stainless steel.
Ambient temperature from -20°C to +70°C.(Max.humidity: 90%). Vibration: XYZ 10g. 2-34Hz,30min.
CENTRONIK. Integral control unit (Option)
Maintaining the concept of modularity, theCentronik unit can be mounted on 480 seriesactuators, both directly or separately on a wallbracket. This way all the control and digitalcommunication characteristics of the Centronikunit, including the standard Fieldbuses(ProfiBus,ModBus, etc.) are available.
SWITCHING and SIGNALLING OPTIONS.
Using modules a number of options can beincluded in the basic configuration: extralimit/torque switches, potentiometer, 4-20mAposition transmitter, Local Control station...
