ACTUATOR INSTALLATION
1) Isolate valve body if already installed in piping.
2) Top of valve shaft has line that indicates plug position. Valve is open when line is parallel to pipeline, valve is closed when line is across the pipeline.
Turn valve shaft CCW (looking down on shaft) until plug is in full open position. Note shaft location. Shaft adapter must be on valve shaft.
3) Operate actuator to full open position.
4) Position actuator in desired orientation.
5) Place actuator over valve shaft and onto valve. Shaft must be in full open position.
6) Install fasteners in actuator base hand tight. Twist actuator CW (looking down on actuator) to take play out of actuator mounting in the closing
direction, then tighten fasteners to secure actuator to valve.
7) Operate actuator to open and close valve and check that valve responds through rated travel in relation to changes in input signal.
8) If isolated, return line pressure to valve and check operation.
ACTUATOR REMOVAL
1) Isolate valve body if already installed in piping.
2) Operate actuator so valve is in full open position.
3) Remove fasteners holding the actuator to valve.
4) Remove actuator from valve. Shaft adapter must remain on valve shaft.
