2) Mounting
Basically there is no limitation in orientation of mounting of actuator on valve, but in the vertical pipeline, cable
conduit of actuator is recommended to be oriented toward ground in order to avoid water flow in through cable
entry. When actuator is mounted on valve, following procedure is recommended.
1> Noting the indicator, position actuator at fully closed position (Clockwise).
2> Valve stem must be properly machined to match the female drive shaft of actuator.
3> Close the valve and mount actuator on valve
4> Both the mounting holes of the actuator and valve flange must be properly aligned with each other.
5> If both are not properly aligned, make manually operate the actuator until aligned.
4. Setting
1) Tools required
- L-Wrench 1 set(M2, Metric)
2)
Manual operation
Manual drive shaft located at bottom of actuator.
Clock wise direction is close, counter clockwise is open.
The fully closed position to fully open position requires about 9 turns.
Be careful not to operate the actuator past the setting of the limit switch.
3)
Limit switch setting
1> Position actuator at fully close position while watching indicator.
2> Turn the Close cam until cam activate the lever of limit switch and makes a “click” sound.
3> Tighten cam set screw (M2) to fix cam position.
4> Do the same way for open position
