CHECKS TO BE CARRIED OUT UPON DELIVERY

4.1 

Damages during transport

Check the packaging and the actuator for damages during 
transport.

Remove the packaging, taking care that some of its 
components (straps, nails, wood splinters, etc.) do not cause 
injuries to the operator.

Once the packaging has been entirely removed, visually 
inspect the actuator for damage.

If accessories are included in the provision, ensure that they 
are compliant to those listed in the order and in the shipping 
documents.

 If the actuator is seriously damaged, do not try to 

repair it or start it up. Please contact Rotork.

4.2 

CE marking and nameplates

The actuator body is cast-embossed with the manufacturer’s 
name and the model’s name. Each actuator is delivered with 
a standard label.

For actuators delivered within the European Union, the CE 
mark the product conformity with the essential applicable 
health and safety requirements of the European Directives.

Supplementary nameplates are applied externally on the 
centre body cover and displays the following data:

•  CE conformity marking

•  ATEX protection

•  Name of technical file deposited with a certifying body

Figure 2: CE ATEX nameplate

Note: 

The TX surface temperature class is not supplied 

since the actuator has no internal heat source. Maximum 
actuator temperature is near the environmental or exercise 
fluid temperature, whichever is greater. Normal operating 
temperature is approximately -20 °C to +80 °C. The precise 
temperature range is specified within the project-specific 
technical documentation. Special applications out of previous 
range are available upon request.

The ATEX nameplate does not indicate the maximum 
environmental and/or exercise fluid temperature; this 
information is reported within the project-specific technical 
documentation.

Contents of the standard nameplate:

•  Name and address of the manufacturer

•  Model type

•  Serial number

•  Month/year of manufacture

•  Maximum/minimum operating pressure (bar)

•  Maximum/minimum operative temperature (°C)

•  IP protection class

Figure 3: KT-XX-DA/SR standard nameplate for units made in 
USA and China

If CE (PED) marking is required, the following data is specified 
on a third plate:

• 

CE conformity marking

• 

PED 97/23/CE category

• Fluid

• 

Design pressure PS (bar)

• 

Testing pressure PT (bar)

• 

Design temperature TS (°C)

• 

Volume (litres)

• 

Certifying body number if applicable

Figure 5: Spring housing warning nameplate

Please check if the data stamped on the plate coincide 
with those specified on the Confirmation of Order, Test 
Certificates and the Delivery Note.

Ensure that the product specification as noted on the 
nameplate(s) is suitable for the application.

 It is not allowed to remove or modify the 

nameplate(s). The nameplate must be kept legible 
at all times: it must be regularly cleaned. In case the 
nameplate is damaged and illegible, a duplicate is to be 
requested.
