1 - Spring Compression Tool JC5389

Disconnect Power From Actuator
Disconnect the air line attached to the actuator and cap it to prevent control
system operation problems. Make sure that the pressure in the actuator has
been relieved.
Removal Of Actuator
The V-3000 is easily removed by loosening the set screw and lifting the actuator
off of the valve. Caution: The spring under the actuator is attached to the valve
and is pre-compressed. Unknown damage to the valve stem may create a
hazardous condition.
Removal Of Spring
                                                Note the position of the stem
                                                extension relative to the stem
                                                and the lower spring plate
                                                relative to the valve body for
                                                later use in reassembly. Place
                                                the locking base of tool JC5389
                                                over the spring and attach it
                                                securely to the valve bonnet
                                                using the two knurled set
                                                screws (See Fig. 2). Insert the
                                                spring compressor portion of
                                                tool JC5389 over the spring and
                                                using hand pressure, engage
                                                the two parts of the tool
                                                together. Use a wrench to hold
                                                the stem extension while
                                                loosening the stem locking

                                                screw with a screwdriver.
                                                Unscrew the stem extension.
Using hand pressure, carefully disengage the top half of tool JC5389 and allow
the spring to expand to its relaxed position. Remove the upper spring plate,
spring, lower spring plate, and the compression tool from the valve.
Re-installation of Actuator & Spring
Perform reinstallation of the actuator in the reverse order as described in the
section titled Removal of Actuator & Removal of Spring.
Re-Commission Valve/Actuator
When spring and the particular actuator is reinstalled, check the following items;
1. Verify all threaded parts are tightened as described in this document.
2. Verify that when power or air is applied to the actuator, the valve stem moves
   to its full up or down position.
