Type 51/52/53 Cylinder Actuators
Connecting Double Acting (Model 51)
(Figures 14 & 15)
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 12.
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.
