6.2. Product assembly

The electromotive linear drive consists of a brushless DC motor, a gear and a spindle system that transfers the force to the control

cone. The integrated control electronics are controlled either by standard signals (analogue) or via a field bus (digital). A position-

er and a process controller are available as controller versions. The electromotive linear actuator is designed to provide optimum

efficiency. At the same time, it keeps the valve tight 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, which can be 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 either via 2 capacitive keys and 4 DIP switches or optionally on a

display with touch screen. 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 3361 offers the operator options for process monitoring, valve diagnosis and preventive mainte-

nance. Internal measurements of the operating status are evaluated and, if necessary, issued as a warning or error message. These

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

storage device. A special feature of the Globe Control Valve is the screwed-in valve seat, which can be replaced to reduce the seat
