Dismantling and Demolition
Before starting the disassembly, a large area should be created around the actuator so as to
allow any kind of movement without problems of further risks created by worksite.
!
WARNING
Before disassembling the actuator, it is necessary to close the hydraulic feed line and
discharge oil pressure from the cylinder of the actuator, from the control unit and from the
accumulator tank, if present.
If the actuator is still mounted onto the valve, loosen the threaded connections between
valve and actuator (screws, tie rods, nuts).
Lift the actuator using the proper lifting points, see Section 2.2.
If the actuator needs storage, before demolition, see Section 2.3.
!
WARNING
The demolition of the actuator both concerning any electrical and mechanical part should
be made by specialized staff.
Separate the parts composing the actuator according to their nature (e.g. metallic and
plastic materials, fluids, etc.) and send them to differentiated waste collection sites, as
provided by the laws and provisions in force.
