Mechanical Installation
The valves are tapped in NPT and should be sealed with an
approved pipe sealant. Torque should not exceed 75 lb-ft.
See Fig. 1 and 2 for valve dimensions. Refer to actuator
literature for actuator dimensions.
Mounting Plate Adjustment
The Actuator Mounting Plate can be rotated to a different
position for installation in confined spaces. This is
accomplished as follows:
1. Remove the handle from the shaft and set it aside.
2. Remove the two screws that hold the stem assembly to
the mounting plate and set them aside.
3. Remove and set aside the stem assembly.
4. Remove and set aside the two screws that attach the
mounting plate to the valve.
5. Remove and set aside hold-down ring from mounting
plate.
6. Rotate mounting plate around valve top to the desired
position.
NOTE: Take note of the screw hole positions on the valve.
They limit the mounting plate positions.
7. Lower ring down to valve body and engage it in the new
position relative to the mounting plate.
8. Tighten screws to valve body securing the mounting
plate.
9. Reattach the stem assembly to the mounting plate.
10. If desired, replace the handle on the shaft.
NOTE: See Fig. 19 for valve exploded view.
Electrical Installation
