10. Release the pressure in the actuator. Use pointer (7) to
set the travel scale (9) to the actuator supply pressure so
that the two stem connectors come into contact. Then
tighten the socket head cap screws (5), hex nut (1), and
lock nut (32).
11. Shut off the closed valve pressure and check that
operation is correct.

Type 51/52/53 Cylinder Actuators
Connecting Double Acting (Model 51) (Figures 10 & 11)
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 7.

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.
Connecting Air to Extend (Model 52) (Figure 9)
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. Extend the actuator stem either pneumatically or with
a handwheel approximately .1” (2mm) using the visual
stroke scale as shown in Figure 7.
5. Assemble the Split Clamp (22).
Note: If the split clamp does not engage with both
stems, then extend the actuator stem until alignment
and engagement is achieved.
Make sure the valve is fully extended.
