1.1 Intended use
Baelz 373-E07 motorized linear actuators are controlled by three-point control or constant
control in combination the digital positioner baelz 7020. The linear actuators of the series
described in this document are intended for the stroke adjustment of valves.
Toensuretheirintendeduse,makesurethattheabovetypeidenticationcomplieswith
the nameplate of the linear actuators before starting any activities. The actual technical
specicationsofthelinearactuatorsandthepowersupplyrequirementsarethespecications
indicated on the nameplate.
Anyuseotherthantheintendedusementionedabove,di󰀨erenttasks,andoperationwithother
power sources than those permitted, is considered to be improper use. In case of improper
use, the operator shall be solely liable for the risk presented to persons and the device as well
as other property!
Intended use also includes compliance with accident prevention and DIN VDE regulations as
well as safe working practices for all measures described in these operating instructions, taking
into account the usual technical regulations.
1.2 Instructions for the operator
Always keep the operating instructions available at the place where the actuator is used!
During installation, operation and maintenance, observe the applicable occupational safety,
accident prevention and DIN VDE regulations. If necessary, observe additional regional, local
or internal safety regulations.
Make sure that every person entrusted with one of the measures described in these operating
instructions has read and understood these instructions.

1.3 Personnel
Onlyqualiedpersonnelmayworkonthislinearactuatororinitsvicinity.Qualiedpersons
are deemed to be persons who are familiar with the installation, assembly, commissioning and
operationormaintenanceoftheactuatorsandhavetheappropriatequalicationsfortheirjob.
Necessaryorprescribedqualicationsinclude,butarenotlimitedto:
●Training / instruction and the authorization to switch electric circuits and devices /
systemsonando󰀨inaccordancewithEN60204(DINVDE0100/0113)andthe
technical safety standards
●Training or instruction in the care and use of appropriate safety and work protection
equipmentinaccordancewithsafetytechnologystandards.
●First aid training.
Work in a safe manner and avoid any operation that would endanger the safety of persons or
damage the linear actuator or other property in any way.
1.4 Before starting work
Beforecarryingoutanywork,checkwhetherthetypesspeciedherecorrespondtothe
information on the name plate of the actuator:
baelz 373-E07
1.5 During operation
Safe operation is only possible if transport, storage, assembly, operation and maintenance is

1.5.1 Transport, installation and assembly
Observe the general installation and safety regulations for heating, ventilation, air conditioning
andpipingsystems.Usetoolsonlyfortheirintendedpurpose.Weartherequiredpersonaland
otherprotectiveequipment.
1.5.2 Maintenance and repair
Prior to maintenance or repair, make sure that the linear actuator is disconnected from power
byqualiedpersonnelinaccordancewithDINVDEstandards.TheE07isalowmaintenance
linear actuator. Depending upon usage, it may be necessary to occasionally grease the
actuator spindle with „Gleitmo 805“.

4. ASSEMBLY
Make sure that the specications on the nameplate correspond to those in
the order documents!
4.1 Fitting position
Whenttingwiththeconnectingrodinhorizontalposition,tthelinearactuatorsuchthatthe
sides of the yoke are positioned one above the other in the vertical plane.
●Allow for about 140 mm space above the cover at the site of installation.
● Checktheworkenvironmentbeforettingtheactuatorandputtingitintooperation:
●Make sure that the valve is correctly installed. For detailed information, refer to the
valve's installation instructions.
●Determine the mounting position of the linear actuator. Do not mount linear actuators
"headdown"belowthevalve.
