Assembly and disassembly of linear units on valves
In the following two subsections, the procedures for assembly and disassembly of linear units on valves are
explained step by step.
4.1
Security and assembly instructions
The device may only be mounted and commissioned by qualified personnel!
Qualified personnel within the meaning of this operating manual are persons who are familiar, with as-
sembly, commissioning and operation of this product, and have the required appropriate qualifications
for this activity.
For assembly and disassembly of the linear unit, the pipes where the valve is installed on
have to be depressurized! If the actuator is removed from the linear unit, the position of the
valve stem won’t be fixed anymore and will be lost due to the linear units non self locking
property.
The linear unit has end stops on both end positions. Do not move against the end stops in
electrical operation! The end limits of the actuator must be set accordingly!
