Y20EBD Valve Linkage for M100 Motor Actuators 11
1. Remove the screw, washer, and nut securing the left and right side
brackets to the base bracket.
2. Position the yoke, left side, and right side brackets as determined
previously. The pins on the side brackets will fit into the holes in the
yoke until the screw is inserted.
3. Install the screw, washer, and nut to secure the side brackets to the
yoke and tighten.
Note: The Y20EBD Linkage Kit can be used on Barber-Colman 1-1/2 to
2 inch valves. Use the grooved adapter bushing provided with the
linkage kit for V-90 Series and the mid-bracket position. Larger
Barber-Colman valves can mount onto the Y20EBD yoke directly;
however, adding locally purchased large washers under the linkage
bracket to prevent paint damage is recommended.
To mount the yoke on the valve:
Valve
Spring Plate
Packing Nut
Yoke Nut
Y20D1-09
Figure 9: Preparing Valve
1. Remove the yoke nut (if present), packing nut (if necessary), and
spring plate (if present) from the valve as shown in Figure 9.
Note: Valves with 1/4 inch stems use the furnished yoke nut having a
3/4 inch thread to install the bushing and secure the bracket.
Larger valves have a one inch packing box thread on the yoke
which fits the smaller hole bushing and requires a separate yoke
nut that is usually furnished with the valve.
