ORMATION TECHNICAL DATA
Technical data / possible extensions
CONSTRUCTION AND FUNCTIONS
According to the operating conditions, different process valves
from the Bürkert programme can be combined with the
TOP
Control Continuous. Suitable alternatives are slanted and
straight seat control valves, diaphragm or ball valves.
Overview
FLUID CONNECTION ELECTRICAL CONNECTION
Control air connection Connections
Position controller
The position of the drive (stroke) is controlled
corresponding to the position set-point. The position set-
point can be predetermined by an external standard
signal.
Process controller (option)
The TOP Control Continuous is combined in a control loop.
The stroke of the valve is calculated from the process set-
point and the process actual value via the control
parameters (PID controller). The process set-point can be
predetermined by an external signal.

Installing the valve
• Installation attitude optional; preferably as above.
• Take note of the flow direction; generally applicable for control
valves: Free-stream under seat!
• Make sure pipelines are free of all dirt and contamination!
• Make sure the pipelines are aligned before connecting the valve
housing.
• In the case of welded housings, be sure to remove the drive
before welding in the housing.
