Actuator to Valve Installation

!
Actuator must be isolated pneumatically and electrically before any (dis)assembly starts.
Stay away from moving parts to prevent serious injuries. When test cycling the actuator
and valve assembly by applying pressure to the A or B port, be aware that there are moving
parts like pinion top, actuator to valve coupling and the valve- blade, ball, plug, etc.
NOTICE
The actuator is designed to be installed, commissioned and maintained using generic tools
like wrenches, Allen keys and screwdrivers. For the removal of inserts, a special extractor
tool can be supplied on request.
During assembly to the valve, do not hit with hammer on pinion top. This can damage the
pinion top washer and cause premature failure.
Before mounting the actuator on the valve or valve bracket, be sure that both the actuator
and the valve are in the same closed or open position.
Refer to Appendix B, Tool and Torque tables, for using the right size tool.
