Actuator  can  be  lifted  and  installed  also  in  horizontal  position, 
according to the valve and pipeline installation. 

To lift the actuator in horizontal mode: 

 

Remove the two plugs on threaded holes, that will be 
used for lifting, on bottom and end flange. 

 
 
 
 
 

 

 
 
 
 
 
 

Figure 5: Holes for horinzontal lifting 

 

 

Install two lifting lugs of proper dimensions on 
apposite threaded holes on bottom and end flange 
(lifting lugs are not provided with the actuator) 

 

Hook a double chain sling on the lifting lugs as shown 
in Figure 6 

 

 
The actuator must remain horizontal; balance the load. 
 

 

 

Angle β must between 0° and 45° as shown in Figure 4
