1. Remove the electrical and pneumatic supplies from the TopControl.
2. Pull off the pneumatic hose between TopControl and actuator at
control connection of actuator.
3. Control function A:
Pressurize the lower pilot air port of the actuator with compressed air
(6 bar),
so that the plug is lifted from the valve seat and is not damaged.
Control function B:
With control function B, no compressed air must beapplied for this
purpose.
4. Remove the actuator in the open valve position by unscrewing the
nipple from the valve body.
5. Before reinstalling the actuator (in the open valve position), grease the
nipple thread with stainless steel lubricant,
e. g. Klüberpaste UH1 96-402 from company Klüber.
6. Replace the graphite seal.
7. After tightening the threaded nipple, align the pilot air ports by turning
the actuator.
INSTALLATION OF THE VALVE
NOTE When using in an aggressive environment, you are advised to connect pneumatic hoses to all
free control connections and place their other ends in a neutral atmosphere.
threaded
nipple
May be installed in any position, but preferably with the actuator above.
Observe the flow direction - general rule for control valves: flow direction: Below seat
Clean the piping of contamination!
Before connecting the valve body, take care that piping is aligned!
In the case of weld-end bodies, be sure to remove the actuator before welding.
ATTENTION! The valve must be for this in the opened position.

Procedure for TopControl Type 8630

2702 - 15
Commissioning
english
Dismount the piston actuator as described below. You will avoid damage to the gaskets because the piston
will be brought into the upper position.
Connect compressed air at 4.5 to 6 bar to P (1).
Remove the blowout mouthpiece.
Unscrew the 4 screws.
Open the cover (2).
The 2 red switches for emergency manual actuation
(3) are located next to the terminal strip.
They are in the idle position when the arrow is paral-
lel to the terminal strip.
Turn the 2 switches carefully 90 degrees in the
clockwise direction (in either order) (4a).
The piston moves into the upper position and the
plug is separated from the valve seat.
Turn only the upper switch to the idle position
(4b).
The piston stays in the upper position even after the
compressed air is switched off.
Procedure for SideControl Type 1067

16 - 2702
Commissioning
english
Remove the valve body from the piston actuator.
The plug is now in the upper position.
This means the gasket will not be damaged.
plug
Weld the valve body.
Clean the valve body carefully.
RECOMMENDATION
Mount the valve body with a new sealing ring bet-
ween the valve body and the piston actuator.
Turn the lower switch back into the idle position.
The piston actuator is bled and the spring closes the
valve.
NOTE This procedure causes air to be trapped under the spring-loaded piston.
Normally the air will escape slowly.
After 10 hours, however, this procedure should be completed.

The control valve is driven by compressed air via the TopControl.
Remove the protective caps from the connectors on the TopControl and the valve.
Apply the supply pressure to port ”1”.
The supply pressure necessary for complete opening or closing of the valve may lie between the minimum
values of 3 and 6 bar, depending on the actuator. The permissible maximum value for the control pressure is
7 bar. The values for the pressure supply are given under pPilot on the rating plate of each control valve.
Attach the exhaust line or silencer to port ”3”.
Control medium: instrument air, class 3 to DIN ISO 8573-1
PNEUMATIC INSTALLATION FOR TOPCONTROL TYPE 8630
Fluid connections of the TopControl Continuous
Remove the protective caps from the valve
and the TOPControl Continuous.
Apply the supply pressure to connection “1“
(3..7 bar, instrument air, free from oil, water
and dust)
Attach the exhaust line or silencer to
connection „3“
NOTE Maintain the applied supply pressure, without fail, at least 0.5 - 1 bar over that required to
bring the pneumatic actuator into the end position. This assures that the control behaviour in
the upper region of the stroke will not be significantly affected negatively if the pressure diffe-
rence is too small.
Keep variations in the supply pressure as low as possible during operation (max. ± 10%).
With larger variations, the controller parameters calibrated with the AUTOTUNE function will
not be optimal.

ELECTRICAL CONNECTION - MULTIPOLE CONNECTORS
(TOPCONTROL TYPE 8630)
NOTE Use of the 4 - 20 mA setpoint input
If the voltage supply of a TOPControl device fails in a row of such devices connected in
series, the input of the failed device will become high-impedance. This will cause the 4 -
20 mA standard signal to fail. If this occurs, please contact Bürkert Service directly.
With Profibus DP or DeviceNet:
The markings of the multipole plugs and sockets, and the contacts are to be found in the
respective chapters.
ATTENTION! For connection to the technical earth (ground) (TE), a threaded stud with nut is provided on
the connection module. To assure electromagnetic compatibility (EMC), connect this stud to
a suitable earthing (grounding) point using as short a cable as possible (max. 30 cm).
