6.2. Product assembly

The electromotive linear drive consists of a brushless DC motor, a gear and a spindle system that transmits the force to the pendu-

lum plate. The integrated control electronics are controlled either via standard signals (digital) or via a fieldbus (digital). It is designed

to provide optimum efficiency. At the same time, it keeps the valve sealed and in position even at the maximum specified medium

pressure in a powerless standstill. An optional energy storage device (SAFEPOS energy-pack) is available for the device. If the supply

voltage fails, it supplies the actuator with the energy required to move the valve into the desired position; this is set in the menu.

The valve position can be changed manually in 2 ways. Either via the electrical manual control or via a mechanical manual control if

no supply voltage is available.

The device can be set and operated via 2 capacitive keys and 4 DIP switches. In addition there is always the possibility to operate

the device via the büS service interface and using the “Bürkert Communicator” software.

The intelligent process valve Type 3320 offers the operator options for process monitoring, valve diagnostics and preventive mainte-

nance. Internal measurements of the operating status are evaluated and issued as warnings or error messages, if necessary. These

indicate, for example, impermissible ambient and process conditions, functional deviations of components or the status of the energy

storage device.
