11 Removal
The work described in this section is only to be performed by
fully trained and qualified personnel only.
Before removing from the valve, make sure the actuator is put
out of operation. Refer to section 10 ‘Decomissioning‘.
Risk of bursting due to incorrect opening of pressurized
equipment or components.
Pneumatic actuators are pressure equipment that may burst
when handled incorrectly. Flying projectile fragments or com-
ponents can cause serious injury or even death. Before wor-
king on the actuator:
Î Before starting any work on the actuator disconnect all
pneumatic / hydraulic / electrical supplies and discharge
the pressure from the actuator.
Risk of personal injury during actuator air exhaust.
In case of pneumatic version the actuator is operated with air.
As a result, air is exhausted during operation.
Î Wear eye and hearing protection when working near the
actuator.
Risk of personal injury due to preloaded and compressed
springs.
End caps are under tension due to compressed springs.
Furthermore incorrect spring cartidges disassembly could re-
sult in serious injury.
Î Before starting any work on the actuator disconnect all
pneumatic / hydraulic / electrical supplies and discharge
the pressure from the actuator.
Î Make sure that the actuator is in the closed position (0°).
Crush hazard arising from moving parts.
The actuator and the valve assembly contains moving parts,
which can injure hands or ngers.
Î Do not touch or insert hands or nger into moving parts.
Î Before starting any work on the actuator disconnect all
pneumatic / hydraulic / electrical supplies and discharge
the pressure from the actuator.
Î Do not impede the movement of the pinion and the pistons
by inserting objects into the actuator.
