1. General
•These instructions contain important information on installing, maintaining and operating the drives
safely and properly.
•Observing them helps avoid dangers, reduce repair costs and downtimes and increase the reliability
and service life of the drives.
•The instructions must be read and used by everyone who is entrusted with working on the drives.
•The instructions must be available at all times. Always keep a copy of these instructions at the
location where the drives are used. Before you start to carry out assembly or maintenance work, you
must read through the instructions in full beforehand. If in doubt, contact AMG-Pesch.
•We reserve the right to make technical changes and additions to the instructions.
•Responsibility
oManufacturer
Safe design/drive layout
Forwarding of all necessary documents, information, certificates
Compliance with all regulations, guidelines
oOperators
Forwarding of all documents, information and certificates supplied / required by
AMG-Pesch to the system operator / operating personnel
•Notes
oIn the following instructions, the valve / drive / accessory unit is referred to as the "actuator".
oIn addition to these instructions, all manufacturer documents (connection diagrams, etc.) for
additional modules must be observed; any missing documents must be requested.

2. Safety instructions
•The basic requirement for safe handling and trouble-free operation of the drives is
knowledge of the safety instructions in this manual.
•During all work, the company safety regulations, environmental regulations and accident
prevention regulations must be observed.
•When handling oils, grease and other chemical substances, the applicable safety
regulations must be observed.
•Used lubricants are to be disposed of properly and in an environmentally friendly
manner. National regulations must be observed.
•The drives may only be operated if they are in perfect working order.
•Use outside the parameters specified in section 5. Technical data and
section 4. Intended use are not permitted.
•The drives may only be operated with the control pressure specified on the nameplate,
see section 5.2. Nameplate.
•The safety devices in the system for limiting the control pressure are to be checked
regularly for their functionality.
•Additional documents from the drive manufacturer / the manufacturer of the attached
components must be observed.
•All work may only be carried out by specialists from AMG-Pesch or appropriately trained
personnel.
•All work on the drive and the associated attachments may only be carried out in the
dismantled / de-pressurized / vented / de-energized state.
•Drives with explosion protection are marked in accordance with section 6. Marking DIR
2014 / 34 / EU + EAC (TP TC 012/2011).
•The drives with labelling according to DIR 2014 / 34 / EU may be operated as Ex
devices under the following atmospheric conditions (DIN EN IEC 60079-0):
-20°C to +60°C
•The temperature of the compressed air supplied must not exceed 45 ° C.
•Filter the control medium with a mesh size of at least 40 µm (ISO 8573-1, class 5).
•Appropriate measures must be taken for applications ≤ 0 ° C.
•Replacement of spare parts only with original parts from AMG-Pesch.
•In the case of single-acting drives, disassemble only in the safety position. (see section
7.2.2. SAF / SAF-HP (single-acting), spring released = safety position)
•With single-acting drives, it must be ensured that no moisture or corrosive media can
penetrate into the outer chamber through the pneumatic connection (see section 7.5.1.
Air supply). (e.g. through filters, silencers)
→Risk of spring breakage
•The pinions of the standard drives are not suitable for absorbing external transverse
forces.
•The drives cannot absorb any permanent torsional vibrations in the end positions.
•The locking ring must be checked prior to functional tests with the control medium; see
section 7.4. Exploded view / item 403 →The pinion can be pushed out of the housing if
the circlip is missing / defective
→Risk of injury

7. Design
7.1.General
•The drive is an essential component of an actuator (valve + drive + control valves ...).
•The drives are used to automate fittings (ball valve, flap, control flap ...).
•The transfer of a thrust to a rotary movement takes place via two opposing pistons with cast racks.
The compressed air and the spring force act via the pistons on the pinion and thus initiate the rotary
movement.
•The main difference to competing products is the use of additional guide rods (see section 7.4.
Exploded view / position 050), which considerably increases the mechanical load capacity of the
drives.
•The SAD / SAF drives have been type tested in accordance with DIN EN 15714-3.
•Swivel angle
oThe drives do not have adjustable end stops as standard
oIn terms of design, 90 ° drives allow the following angles of rotation as standard:

•The drives are tested according to protection class IP67 according to EN 60529.
•Single-acting actuators allow safe assembly / disassembly through the use of “tied up” and “pre-
tensioned” safety spring assemblies (> size 10).
oFor size ≤ 10, safety is guaranteed by using "long" cover screws.
7.2.Type
•See also document QH-101dt_Variants-SAF_SAD
7.2.1. SAD/SAD-HP (double-acting)
•Description
oDouble-acting double-piston rotary actuator without internal reset function.
oDouble-acting actuators remain in the current position if the control pressure fails.
Safety function
Torque curve
The safety function lies in the
requirement to assume the desired
position of the drive in order to shut
off or release a volume flow.
This requires a corresponding
control on the system side.

7.5.Interfaces / connections
7.5.1. Air supply
•AMG double-piston rotary actuators have the NAMUR interface as standard for direct flange-
mounting of control valves in accordance with VDI / VDE 3845. The air connections are marked with
"2" (inner chamber) and "4" (outer chamber).
OPEN CLOSE
•The use of control valves with NAMUR connection is recommended
oUsing a coding pin (see VDI / VDE 3845-1, 3.2.2) ensures the prescribed position of the
control valve.
•For connection dimensions, see also section 5.1. Limits of use and technical data sheets
•For recommended control see document QH-101dt_Variants-SAF_SAD

7.6.Manual operation
•There is the option of installing an emergency manual gearbox between the drive and the
valve. The valve interface is used for assembly (see 7.3.3). The manual emergency gear
must meet the following requirements:
oThe manual actuation forces must comply with EN 12570.
oThe handwheel / hand lever must remain stationary when powered.
oThe current operation must be switched off before manual operation is initiated.
oThe closing / opening directions for manual operation must be clearly marked; the closing
direction must be clockwise unless otherwise specified.
7.7.lubrication
•To protect the drives and to ensure that they function properly, we only recommend the use of original
AMG Pesch lubricating greases.
•The following types of grease are used
oType SAD/SAF
Temperature range
Type of grease
Standard
-25°C / +80°C

1) see section 5.2. Nameplape
2) Values apply to 90° drives; for 180° drives multiply by factor 2
7.8.Stroke limitation
•Stroke limiting module
•The BR16 series is equipped with an interface for the AMG Pesch stroke limiter module as
standard.
•The assembly takes place without a centring ring; see section 7.6.3. Valve interface.
•The stroke limitation module is used to adjust the swivel angle of the drive.
•For more information, see also HBM dimension sheets
