! NOTE: If mounted properly, the follower arm should be

horizontal when the valve is at 50% stroke and should move

approximately ±30° from horizontal over the full stroke of the

valve. If mounted incorrectly, a stroke calibration error will

occur and the indicator lights will blink a RGGY code indicating

the position sensor has gone out of range on one end of travel.

Reposition the feedback linkage or rotate the position sensor to

correct the error.

5.2 Mounting to Standard

Valtek Rotary Valves

(See Figure 4)

The standard rotary mounting applies to Valtek valve/actuator as-

semblies that do not have mounted volume tanks or handwheels.

The standard mounting uses a linkage directly coupled to the valve

shaft. This linkage has been designed to allow for minimal misalign-

ment between the positioner and the actuator. The tools required for

the following procedure are:

•

⁄32" Allen wrench

• ½ " open-end wrench

•

⁄16" open-end wrench

•

⁄8" socket with extension

•

⁄16" nutdriver

1. Fasten the spline lever adapter to the splined lever using two 6 x

½ " self-tapping screws.

2. Slide the take-off arm assembly onto the spline lever adapter

shaft. Insert the screw with star washer through the take-off

arm and add the second star washer and nut. Tighten nut with

socket so arm is lightly snug on the shaft but still able to rotate.

This will be tightened after linkage is correctly oriented.

3. Attach follower arm to positioner feedback shaft using the star

washer and 10-32 nut.

! NOTE: The arm will point up when feedback shaft is in the free

position.

4. Using four ¼ -20 x ½ " bolts, fasten positioner to universal

bracket using appropriate hole pattern (stamped on bracket).

5. Using a ½ " end wrench and two

⁄16-18 x ½ " bolts, attach bracket

to actuator transfer case pad. Leave these bolts slightly loose

until ﬁ nal adjustments are made.

6. Rotate take-off arm so the follower pin will slide into the slot on

the take-off arm. Adjust the bracket position as needed noting

the engagement of the follower pin and the take-off arm slot.
