DVC6200 Digital Valve Controllers

9. Install the plug (1/4 NPT, included in the mounting kit) to the external output pneumatic port A.

10. Using a 5 mm hex wrench, attach the digital valve controller to the GX actuator mounting pad on the side that has

the open pneumatic port. Be sure to place the O‐ring between the digital valve controller's pneumatic output and

the actuator mounting pad. Pneumatic tubing is not required because the air passages are internal to the actuator.

11. Check for clearance between the magnet assembly and the DVC6200 feedback slot.

12. If not already installed, install a vent in the port on the upper diaphragm casing's air supply connection on the

actuator yoke leg.

13. For remote mount applications, proceed to page 13 for DVC6205 base unit mounting. Otherwise, proceed to

Step 2—Connect the Pneumatic Tubing on page 15.

For air‐to‐close GX actuators

Vertically align the magnet assembly so that the center line of the alignment template is lined up as close as possible

with the lower

extreme of the valid travel range on the magnet assembly. The magnet assembly should be positioned

so that the index mark on the pole pieces (back of the DVC6200 housing) is within the valid range on the magnet

assembly throughout the range of travel. See figure 9.

7. Tighten the fasteners and remove the alignment template.

Note

Use a flat end hex key to tighten the mounting assembly fasteners to a torque of 2.37 N•m (21 lbf•in) for 4 mm screws, and

5.08 N•m (45 lbf•in) for 5 mm screws. While tightening the fasteners using the hex key should be sufficient, blue (medium) thread

locker may be used for additional security.
