6.2 DISASSEMBLY
When disassembly of actuator is required for maintenance, fi rstly remove the actuator from the valve. Before performing any disassembly operations it is
important to verify that the actuator is not pressurised.
Always use caution and double check that the ports 2 and 4 are vented and are free from any accessory and/or device. When the actuator is a spring return
unit, make sure that the actuator is in the failed position and with pistons completely inwards before disassembling.
