Installation and Set Up
4. On vacuum service, the valve shaft may be drawn into the body by the
vacuum acting on the shaft, but the magnetic coupling must be assembled
flush with the mounting bracket with the shaft pulled fully out to its thrust
bearing. Check that the endplay from the vacuum position to the fully
extended position is less than 0.06 in. (1.524 mm)
5. Slide the magnet holder into the extension shaft. The location of the magnets
is in the ring of the magnet holder. The magnetic axis is the imaginary line
through the center of both magnets.
6. Rotate the magnet holder so that the magnet axis is vertical when the valve is
in the closed position.
7. Align the end of the magnet holder flush with the end of the mounting bracket.
Secure the magnet holder with two M6 set screws.
8. Slide the V-Seal over the magnet holder.
9. Secure the SVI II AP onto the mounting bracket using four M6 x 20 mm socket
head cap screws.
10. Ensure no interference exists with the position sensor protrusion.
11. Ensure that the V-Seal makes contact with the skirt around the position sensor
protrusion on SVI II AP housing.
