3 Use and operating principle
The pneumatic actuator type "PAMS" enables automatic actuation of butterfly
valves.
A piston runs in a housing, its stroke movement is transmitted to a rotary move-
ments of the drive shaft.
The stroke of the piston is limited in such a way that the drive shaft does a 90°
rotation per stroke. This matches exactly the required rotational angle to open or
close the butterfly valve disc in the butterfly valve connected via a flange (figure
1).
With the actuator NC/NO, the compressed air is supplied via a drilled hole G 1/8"
in the lid. The compressed air flows in above the piston and causes the piston to
move down, the butterfly valve disc rotates. The installed springs provides the
return movement of the piston. With the actuator DA, an additional drilled hole
G1/8“ is located at the side in the lower area of the actuator. The return move-
ment of the piston is done by compressed air flowing in. Pneumatic connections
are not part of the delivery.
NC1/NO2
The actuator is charged with com-
pressed air above the piston. On the
other side, air escapes through a vent-
ing hole. Reset movement is done by
spring force.
DA3
The actuator is charged with com-
pressed air either above or below the
piston.
Changes in construction and design due to technical advance reserved.

5 Transport and storage
5.1 Checking the delivery
When you receive the actuator, check the information on order and
delivery papers to make sure they correspond.
Check that the delivery is complete, and check its condition.
If there are visible signs of transit damage and/or packing units are missing, notify the forward-
ing agent immediately in the consignment note. You (the recipient) should take recourse
against the forwarding agent immediately in writing, and M&S Armaturen GmbH must be in-
formed of this action.
Complaints regarding transit damage that is not immediately evident must be made to the forward-
ing agent within 6 days. The recipient must bear the costs for claims made after this period.
5.2 Transport
The packing units/actuators must only be transported using suitable
lifting equipment and slinging gear.
Pay attention to the graphic symbols on the packaging.
Transport the actuator carefully to prevent damage from sudden im-
pacts; exercise due care when loading/unloading.
6 Assembly/disassembly
When carrying out the assembly, make absolutely sure that the butter-
fly valve disc is in the correct position!
Mount the actuator in such a way that it cannot be damaged (e.g. by
transport vehicles).
Observe the relevant national guidelines and regulations.
6.1 Assembly of butterfly valve type SV04 (see figure 1)
Put butterfly valve switch cam (4.1) onto the drive shaft of the pneumatic actuator (1).
Attach bracket SVV04 (3.1) with the hexagon socket head cap screws (5.1) to the pneu-
matic actuator (1) applying a torque of 3Nm.
Push the pneumatic actuator (1) with the mounted bracket SV04 (3.1) and the butterfly
valve switch cam (4.1) over the butterfly valve (2.1) so that the outer square of the butter-
fly valve disc engages precisely into the inner square of the drive shaft of the pneumatic
actuator (1). In doing so, pay attention to the disc position according to table 3.

7 Installation/Commissioning
Pneumatic actuators may only be installed and brought into operation
by specialist personnel who have received the necessary technical
training, and are equipped with the experience and knowledge to carry
out the tasks involved.
Observe the following:
The actuator must be securely connected to the bracket and butterfly
valve.
Lines, valves and drives in pressurised systems must not be detached.
Appropriate measures must be taken to prevent unintentional opera-
tion or unauthorised interference.
Only use clean, dry and oil-free compressed air (see also chapter 9.2).
The pneumatic hoses must be cut at right angles using a hose cutter to
ensure the necessary optimum fit in the plug connector.
8 Repairs/Maintenance
The actuator must not be modified.
The actuator must not be opened.
Careful - tensioned spring!
The actuator is maintenance free.
Assembly/disassembly - see assembly instructions (the butterfly valve
must be included in the potential equalisation).
M&S Armaturen GmbH cannot accept liability for claims made as a re-
sult of nonobservance of these Operating Instructions or constructional
changes to the actuator.
Any other use or use outside the defined scope is considered to be im-
proper use. M&S Armaturen GmbH will not accept liability for losses
incurred as a result of improper use.

12 Optional trigger and query systems
12.1 End position feedback
The bracket SV04 (3.1) and the SV compact bracket (3.2) are equipped with a feedback de-
vice. By the installation of inductive proximity switches M12x1 and a switch cam, the position
"OPEN" and/or "CLOSED" can be queried, respectively.
Figure 3: Butterfly valve type SV04 with pneumatic
actuator and end position feedback
Figure 4: Butterfly valve type Classic with pneumatic
actuator and end position feedback
12.2 Control and feedback head TOP LED
The control and feedback head TOP09 is an extension module for the pneumatic actuator
PAMS. The valve position detection is done by proximity switches. The integrated pilot valve
controls two single-acting actuators. In case of double-acting actuators, two pilot valves control
the actuator.
The design of control head and pneumatic actuator allows for an internal control air flow with-
out external hoses. Apart from the electric position feedback, the device status is displayed
optically at the control head itself by a mechanic position indicator.
The control and feedback head can be adapted to any M&S standard element. A splashwater-
protected housing contains both the proximity switches for position query and the pilot valves
required for triggering.

12.3 Control head AS-i
The control head AS-i is an extension module for the pneumatic actuator PAMS with an AS-
Interface field bus interface. A contact-free analogue sensor element detects the valve position
after detecting the valve end positions automatically by means of the teach function during
commissioning and storing them. The integrated pilot valve controls single- or double-acting
actuators.

12.4 Electro-pneumatic position controller (EPPC)
With the electro-pneumatic position controller (EPPC) for the pneumatic actuator PAMS, the
actuator position or the valve disc position is controlled according to the set position value. The
set value specification is done by an external standard signal 4 to 20 mA or via AS interface.

actuator and electro-pneumatic
position controller (EPPC)

12.5 Electro-pneumatic process controller (EPPC/PR)
With an electro-pneumatic process controller (EPS/PR) for the pneumatic actuator PAMS, the
actual value of the process factor is directly applied to the device as a 4-20 mA signal. The pro-
cess controller calculates the set value for the position controller by a set/actual value compari-
son.

ic actuator and electro-pneumatic
