3025 Actuator

May 2011

3

If the actuator is equipped with a side-mounted handwheel, also refer to the figures 13, 14, 15 and 16. Figure 13
shows the size P460 and the size P462 side-mounted handwheel, figure 14 the size P460-200 and figure 15 illustrates
the size P900.

CAUTION

To avoid parts damage, do not use a normal operating pressure that exceeds the Maximum Diaphragm Casing Pressure of 4
bar or produces a force on the actuator stem greater than the Maximum Allowable Valve Stem Load.

D

 

Valve/Actuator Assembly:

 If the actuator and valve are shipped together as a control valve assembly, it has been

adjusted at the factory, and may be installed in the pipeline. After installing the valve in the pipeline, refer to the
Loading Connection procedures.

D

 

Actuator Mounting:

 If the actuator is shipped separately or the actuator has been removed from the valve, it is

necessary to mount the actuator on the valve before placing the valve in the pipeline. Refer to the actuator
mounting procedures before placing the valve in service.

D

 

Positioner:

 If a positioner is installed, or is to be installed on the actuator, refer to the positioner instruction manual

for installation. During the adjustment procedures, it will be necessary to provide a temporary loading pressure to
the actuator diaphragm.

CAUTION

The 3025 diaphragm actuators are designed to mount on push-down-to close valves. Do not mount these actuators on any
other type of valve without first contacting your Emerson Process Management sales office.

Mounting the Actuator on the Valve

CAUTION

If the valve stem is allowed to remain in the up position (towards the actuator) during mounting, it can interfere with the
actuator mounting, possibly damage valve stem threads or bend the valve stem. Be sure the valve stem is pushed down
(into the valve body), away from the actuator while mounting.

CAUTION

If the actuator is equipped with a side-mounted handwheel, during mounting it can interfere with the valve stem (even if
the valve stem is pushed completely down into the valve body), possibly damage valve stem threads or bend the valve
stem. Be sure the actuator stem is sufficiently retracted (into the side-mounted handwheel), away from the valve while
mounting. If not, the actuator stem can be retracted by turning counterclockwise the handwheel. Be sure the actuator
stem does not rotate while turning the handwheel (use the anti-rotator to prevent rotation).

1.  Provide a vise or some other method of supporting the valve and the weight of the actuator during assembly. Push

the valve stem down away from the actuator while mounting the actuator.
