Type 51/52/53 Cylinder Actuators
Connecting Double Acting (Model 51) (Figures 13)
1. Install actuator on the valve body with drive nut.
2. Connect manual loading panel tubing to the Top Plate (17).
3. Apply required air pressure through the manual loading panel
to completely extend the actuator stem.
4. Reconnect manual loading panel tubing from the Top Plate
(17) to the Yoke (1), which is integrated into the bottom plate
connection.
5. Retract the actuator stem either pneumatically or with a
handwheel approximately 1” (2mm) using the visual stroke
scale as shown in Figure 11.

6. Assemble the Split Clamp (22).
Note: If the split clamp does not engage with both
stems, then retract the actuator stem until alignment and
engagement is achieved.

7. Assemble and tighten Indicator Arm (23), Spring Lock
Washers (25), and Hexagon Bolts (24).
8. Line up the indicator plate (26), with Indicator arm (23) and
check actuator for proper operation.
