Adjustment
WARNING
Avoid personal injury or property damage from sudden release of process fluid. Before starting adjustment:
D
Do not remove the actuator from the valve while the valve is still pressurized.
D
Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D
Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D
Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D
Vent the power actuator loading pressure and relieve any actuator spring precompression.
D
Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D
The valve packing box may contain process fluids that are pressurized,
even when the valve has been removed from the
pipeline.
Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.
D
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
The only adjustment on the 1069 actuator is to make sure the valve disk or ball is correctly opened or closed when the
lever (key 19, figure 4) is positioned against either of the travel stops. For accurate adjustment of the zero‐degree
position of the valve disk or ball, the control valve must be removed from the pipeline. Refer to the valve body
instruction manual for instructions during this procedure.
If the actuator is equipped with a manual operator, make sure that the manual operator is in the disengaged position
and that the bypass valve (key 53) is closed before performing adjustment procedures.
To adjust the 1069 actuator, perform the following steps. A regulated air supply is required to stroke the actuator
during this procedure. Key numbers referenced in this procedure are shown in figure 4.
Note
When shipped, the 1069 actuator is equipped as specified for either 60‐degree or 90‐degree valve shaft rotation. For 60‐degree
rotation, the travel stop screw (key 9), travel stop nut (key 34), hex nut (key 37), and cap screw (key 46) must be installed as shown
in figure 4. For 90‐degree rotation, two travel stop screws (key 35) and two hex nuts (key 39) must be installed along with a single
cap screw (key 47). Field conversion from 60‐degree to 90‐degree rotation, or vice versa, is possible but the appropriate parts
must first be ordered (see the parts list).
1. Loosen the hex nuts (key 39 and, if used, key 37) on both travel stop screws (key 35 and, if used, key 9) and back out
both screws slightly.
2. Stroke the actuator until the valve disk or ball is in either the open or closed position as indicated by the pointer on
the actuator travel indicator (key 28). If either of the travel stop screws is not backed out far enough to allow
adjustment to either the open or closed position, repeat step 1 of this procedure until adequate clearance is
allowed.
