Electric actuator for quarter turn valves

The Biffi F02 is a compact, intelligent, electric actuator which incorporates all the advanced variables needed to provide effective control in large and complex plants.

The F02 is available as a single-phase or three-phase actuator for on/off and modulating quarter turn valves and is economical in power consumption, and light and easy to install.

The F02 includes, as standard, a range of design features such as a universal motor with an Innovative Power Supply Module that can simply be connected to the local power and will adapt to the available power rating. The motor is S3 100% duty rated as standard, allowing on-site conversion from on/off duty to modulating, if required.

The actuator also incorporates accurate and easily adjustable torque control; contact-less Position Sensor for valve position management; a variable speed control that enables the valve opening and closing speeds to be adjusted independently; and valve position detection with end of travel settings.

An interchangeable base plate and a separate terminal block ensure simple and safe connection to all valve types. The compact design of the F02 provides a balanced actuator, enabling easy connection to small valves, and minimises pipe work stress and loads to the valve shaft.

As well as being economical in its power consumption, the F02 also features inherent flexibility with regard to voltage, torque, speed and mounting variations, all contained in one compact package.

In addition to the standard features, operators have the option to incorporate the latest technological solutions for process control plants, via Field Network systems such as ProfiBus, Foundation FieldBus, AS Interface, DeviceNet and Lonworks. Also, where a Field Network is not installed the operators have the option to utilise Bluetooth wireless connectivity, which provides non-intrusive configuration and diagnostics between the actuator and a PDA or PC.

Biffi F02 actuators are manufactured from die-cast aluminium and feature sintered, epicyclical internal gearing to ensure smooth and reliable operation.

The F02 range comprises six models, for operating at torques of up to 2000 Nm with an operation time from 8 to 400 s. They can be supplied with a full range of quarter turn Tyco flow control valves to provide a pre-assembled and tested product ready for on-site installation.
