•
How to decommission an actuator in a safe way.
7.1
Before You Start
WARNING - MOVING PARTS
Actuator must be isolated pneumatically and electrically before any (dis)assembly starts.
Before mounting or (dis)assembling the actuator consult the relevant sections of this manual.
Actuator can move when removing supply pressure and/or electrical control signal of
actuators. If not already there, a spring-return actuator will cycle to its fail position.
When removing any ball valve or plug valve assemblies from a pipe system, isolate the
piping system on which the Actuator is installed and relieve any media pressure that may
be trapped in the valve cavities before removing the actuator for maintenance.
A spring-return actuator mounted on a valve, which is stuck in mid stroke, contains a
high spring load which will cause a sudden rotation of the actuator versus the valve or
valve bracket during disassembly. This can cause serious injury to personnel or damage
to property.
Refer to Appendix A for instructions to safely remove the spring load before disassembling
the spring-return actuator from valve or bracket.
Important
Refer to the Safety Guide for Lifting Instructions.
