It is essential that mounting procedure is carried out
when the valve is not under working process conditions,
as full valve movement may occur.

It is essential that the actuator is mounted correctly to
the valve, damper or other device.
The Installation & Setup will include the following procedures:
1. Prepare the Drive Coupling.
2. Ensure Valve position is noted and safe (Offline).
3. Mount and align actuator to valve/pump.
4. Carry out Basic Setup.
A suitable mounting flange must be provided to mount
the unit to the valve top works assembly. Mounting flange
assembly fixings must conform to Material Specification ISO
Class 8.8. Delta GZ coated Grade A4 stainless steel fixings
are recommended. CMA Rotary actuators are supplied
with base assembly suitable for Non Thrust applications
requiring between 180 degrees and 320 turns operation.
For applications that require thrust to be taken by the actuator
apply to Rotork Process Controls.
drive Coupling
Machine and fit coupling adaptor to the actuator output shaft
and secure appropriately.
Align and Mount Actuator
Ensure that the actuator/stem coupling is aligned correctly
with the stem of the valve or actuated device. Mount the
actuator to the flange adaptor, ensure that the actuator is
central and there is no mis-alignment between the coupling
and shaft.
