Remove the handle from the shaft and set it aside.
Loosen the wing nut under the mounting plate, which is used to fasten the actuator.
Loosen the coupler set screw of the stem.
Take out the whole actuator box from the mounting plate and set it aside.
Rotate the stem counter-clockwise (CCW) 90º.
Assemble the whole actuator box back to the mounting plate.
Note:
Please notice that the orientation of the tooth on the stem must be matched with the orientation of the tooth
on the shaft sleeve of the actuator.
Screw the wing nut and the fasten bolt of the stem.
Assemble the handle back to the shaft and tighten the screw.
Important
After changing the valve port, please check and make sure that the port A is the supply return common port.

Loosen the coupler set screw of the stem.
Take out the whole actuator box from the mounting plate and set it aside.
Remove the four screws that hold the stem assembly to the mounting plate and set them aside.
Remove the stem assembly and mounting plate, rotate the mounting plate around valve top to a desired position.
(Mounting plate can only be re-positioned in 90º increments.)
Note:
Do not rotate the stem solely while remove the stem assembly and mounting plate.
Place the stem assembly and mounting plate back to the top of the valve, fasten the four screws to valve body,
securing the mounting plate in its new position.
Assemble the whole actuator box back to the mounting plate.
Important
Please make sure that the orientation of the tooth on the stem must be matched with the orientation of the tooth
on the shaft sleeve of the actuator.
