Electric thrust actuator ARI-PACO 1,6 kN
10.0 Dismantlement of thrust actuator
For the disassembly of the thrust actuators, proceed in the following way:
- Release the two recessed screws on the housing, remove the housing carefully upwards.
- Disconnect all leads that enter into the linear actuator and pull them out of the linear
actuator.
- Replace housing carefully from above and mount with two recessed screws on the linear
actuator.
- Loosen the coupling with a wrench (SW24). Take care not to damage the coupling with the
wrench.
- Remove the two hex screws and the linear actuator from the valve.
- Take the linear actuator from the valve.
- Remove the hex socket screw.
- Remove screw socket and coupling from the valve stem.
ATTENTION !
- The supply line for connecting up the thrust actuator must be in the dead state
i.e. disconnected while dismantlement work is being carried out. After being
disconnected, the mains power must be prevented from being switched back
on again accidentally.
- The system must be run down (depressurised state) as the valve cone is not
held without the thrust actuator and would thus be conducted by the system
pressure.
- Valve plug approximately in mid lift position - on no account supported inside a
seat!
