GENERAL INFORMATION
Described in these instructions by way of example, is the
commissioning of a single-acting control valve without field
bus communication.
You will find the detailed description of the device in the
operating instructions for the TOP
8630 also in the operating instructions for the process valves
on the supplied CD.

Safety instructions
• Comply with the generally recognised rules of
practice for the application planning and
operation of the device!
• Installation and maintenance work is only to be
carried out by suitably trained tradesmen using
appropriate tools and equipment!
• Comply with the applicable accident prevention
and safety regulations for electrical equipment
during operation and maintenance work on the
device!
• Always switch off the voltage supply prior to any
interventions to the system!
• Remember that pipelines and valves in systems
which are under pressure must not be opened!
• Take appropriate steps to rule out inadvertent
actuation or unacceptable maltreatment!
• Guarantee a defined and controlled system
restart following an interruption to the electrical or
pneumatic supply!
GENERAL INFORMATION TECHNIC
Safety instructions
ATTENTION EXERCISE CAUTION WHEN
The device contains electronic components which react
sensitively to an electrostatic discharge (ESD). Contact with
electrostatically charged persons or objects will damage these
components. In the worst case they are immediately destroyed
or will fail after commissioning.
Comply with the requirements according to EN 100 015 – 1 in
order to minimise or eliminate the possibility of damage
through an abrupt electrostatic discharge. Take care also not
to touch electronic components when the supply voltage is
applied.
HANDLING!
ELECTROSTATICALLY ENDANGERED
COMPONENTS / ASSEMBLIES
Use for the intended purpose
Comply with the directions in these instructions, also the
operating conditions and permissible data according to
Datasheet Type 8630, to ensure that the device functions correctly and
remains serviceable throughout its life. In the event of noncompliance with these instructions, also of impermissible
interventions to the device, we waive all liability and the guarantee for
the device and all accessory parts is cancelled! The device is
intended exclusively for use as a positioning and process control
system. Any different use or use going beyond this is considered
improper use
use. The risk is carried solely by the user.

FLUID CONNECTION ELECTRICAL CONNECTION
Control air connection
The fixing screw (connection between Top
and process valve) may only
be tightened with a
maximum torque of 1.2 Nm.
Control
Valve
According to the operating conditions, different process valves
from the Bürkert programme can be combined with the
TOP

straight seat control valves, diaphragm or ball valves.
Functions
Position controller
Process controller (option)
Continuous. Suitable alternatives are slanted and
The position of the drive (stroke) is controlled
corresponding to the position set-point. The position setpoint can be predetermined by an external standard
signal.
The TOP
Control
The stroke of the valve is calculated from the process setpoint and the process actual value via the control
parameters (PID controller). The process set-point can be
predetermined by an external signal.
Continuous is combined in a control loop.

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.
