To Disassemble Actuator
Remove position indicator (24) from actuator. 1.
Insert actuator removal tool or other suitable device 2.
and thread into actuator where position indicator
pin was located.
Thread tool completely into actuator. Next,
3.
compress the springs in the actuator by tightening
the wing-nut of the tool onto the actuator. NOTE: if
you do not have the actuator tool mentioned above,
a long screw with a bolt can be used to compress
the spring.
Once the springs are compressed, there will be a
4.
space between the flange (9) and the clip ring (20).
Use snap ring pliers or spanner wrench to remove
5.
the clip ring (20) from the bonnet (2).
Remove the bonnet from the actuator by slowly
6.
loosening the wing nut. BE SURE ACTUATOR
TOOL DOES NOT LOOSEN - TOOL COULD
BE FORCEFULLY EJECTED FROM ACTUATOR,
CAUSING INJURY TO PERSON OR PROPERTY.
Pay attention that the actuator tool doesn’t loosen
7.
when the wing-nut of tool is being loosened.
Once sufficiently loosened and springs are relaxed,
8.
remove actuator tool from actuator.
At this time, the inside of the actuator will be
9.
exposed and seals can be exchanged.
To Access Seating Seal
To access the seating seal (7), simply loosen the 1.
bonnet section (2) from the flange (9). This can be
done after carrying out the previous steps from
actuator disassembly. If done before actuator is
disassembled, it is recommended to supply air to
the actuator to lift the seat from the valve body to
prevent damage to the seating seal (7).
Once the head section is loosened, remove
2.
actuator and piston rod from valve body.
Loosen seat retaining bolt (16) from valve disc (5)
3.
and remove seating seal (7).
Replace sealing for head section (22) if damaged.

the clip ring (20) from the bonnet (2).
To Access Packing Chamber
Note: Previous steps must be carried out beforehand.
Remove the piston (4) from the stem (3) by 1.
removing stem nut (21).
Pull the piston rod out of the bonnet (2) from
2.
below.
The flange (9) should then be removed from the
3.
bonnet (2).
The flange is assembled with an anti-loosening
4.
liquid to prevent it from becoming inadvertently
loosened. Use caution not to damage the
flange, especially at the sealing areas, when
disassembling.
Once the previous steps are completed, the
5.
packing chamber is now accessible.
Ordering Spare Parts
Use only genuine Jordan Valve parts to keep your valve
in good working order. So that we can supply the parts,
which were designed for your valve, we must know
exactly which product you are using. The only guarantee
to getting the correct replacement parts is to provide
your Jordan Representative with the valve serial number.
This number is located on the valve identification tag.
If the serial number is not available, the parts needed
for your valve might be determined using the following
information: Model Number, Valve Body Size, Seat
Material and Cv Rating, Spring Range and Set Point, Trim
Material, Part Name - Number and Quantity.
NOTE: Any parts ordered without a valve serial number
that are found to be incorrect are subject to up to a
minimum 25% restock charge when returned.
