1.2 Requirements for the usage acc. to regulations
The AMG pneumatic double piston rotary actuators serve the automation of ball valves, plug valves,
butterfly valves and control valves. They are designed to operate the rotary movements of the
armature with 90°. The AMG pneumatic double piston rotary actuators are available in types:
Type SADT - double acting with tandem pistons
Type SADF - double acting with spring storage
Type SAF - single acting with spring return
For the safe operation and the proper use, the following measures have to be fulfilled:
Connecting of an control valve on the installation side by a provided control
Only the dry air as a control medium has to be used. The dew point must be at least 10°C
lower than the lowest operating temperature
The maximal temperature of the supply air takes 45°C
The maximal admissible pressure can be accessed from the type plats, 6 bar in standard,
max. 8 bar
The mesh size of the control medium is to filter at least with 40 µm (ISO 8573-1, grade 5)
The actuators are suitable for ambient temperatures from -25°C up to +80°C (special
constructions can deviate from it)
The shafts of the actuators are not appropriate to support external transversal forces
Make sure, that no humidity or water could enter into the pneumatic connection of actuators
Type SADF und SAF with spring return
The actuators are unsuitable for taking permanently torsion vibration in the end position
Do not fall below the minimum switch time of the Actuators, mentioned in table 1.1
By operating with a deviating control medium as the dry air, the manufacturer has to
be absolutely contacted.
Size Min. switch times
45-60 1,0 sec.
50-70 1,0 sec.

1.3 Safety instructions for user
Prerequisite for a safety-oriented workflow and a failure-free operation of the actuators is the
knowledge of the basic safety instructions in this installation and maintenance instruction.
Furthermore, the valid instructions and rules concerning accident prevention and the accepted
standards for a safety-conscious and competent workflow have to be respected. It is not allowed to
use the actuators for another aim than defined by the manufacturer. Obvious risks could be the
consequence. Local standards of working and safety rules always have to be respected. Ensure also
compliance with environmental laws and regulations. Working with oils, grease and other chemical
substances needs to respect the safety instructions of the concerned products. Lubricants have to be
disposed competently and in respecting the environment laws. The national standards have to be
respected. While using the Actuators, the user should obligatory consider the following information
concerning the prevention of occupational risks and should always guarantee their application.
Without respecting the advice contained in these instructions dangers can appear and
lead to the ineffectiveness of the guarantee and liability of AMG-PESCH.
The actuators are to be pursued only in flawless, functional state
The security equipment in the enclosure to the limitation of the pressure is to be checked
regularly for her functional ability
