Field Conversion
For field conversion from fail open (CCW) to fail close (CW) and vice versa, follow the following steps.
NOTE:
• An additional adapter kit is not required for field conversion
• Disassemble the actuator from the valve before carrying out the conversion
THE ACTUATOR IS DISASSEMBLED FROM THE VALVE
a WARNING: Ensure that the pneumatic connection ports of the cylinder are disconnected. Also make sure that
all pneumatic supplies to the control unit and all power supplies are disconnected. Finally, make sure that the
actuator is in fail position.
3.0.1 Starting with the actuator in a fail open (CCW) execution,
remove the actuator from the valve, keeping the spool
adaptor installed onto the valve.
3.0.2 Rotate the actuator.
3.0.3 Reassemble in the new position the actuator onto
the spool piece and the valve. Now the actuator is in
a fail close (CW) execution. Similar steps will apply for
conversion from fail close (CW) to fail open (CCW).
