Note: Personal working on an actuator replacement

should wear safety glasses at all times during this

changeout.

Remove existing actuator and linkage — MP55XX electronic

hydraulic actuator

1. Disconnect all wiring attached to actuator.

2. Disassemble actuator from valve body by unscrewing actuator

from extension.

3. Remove extension from valve body.

4. Using channel locks, compress the spring and square washer

on top of spring. Using a flat head screwdriver, turn the brass

square nut counter-clockwise to release the washer.

CAUTION

: Spring is under compression and brass square

nut and/or spring could be propelled from valve body if not

firmly held.

Note

Remove spring, washer, and brass extension attached to

valve stem.

5. See Figure 4-1 on page 4.

Remove existing actuator — existing DuraDrive actuator

1. Disconnect all wiring attached to actuator.

2. Disassemble actuator from linkage. Loosen the nuts on the shaft

clamp and the anti-rotation shaft.

3. See Figure 5-1 on page 5 for a 2-way valve (STS®, Ultra-sorb® and

steam injection humidifiers). Or see Figure 6-1 on page 6 for a

3-way valve (LTS®).

Assembling linkage to valve — changing from a MP55XX

electronic hydraulic actuator to a DuraDrive actuator.

• Assemble the linkage to the valve, according to Figure 4-1 below.

• Continue the assembly process according to Figure 5-1 on page 5.

Note: Turn to page 5 if replacing an existing DuraDrive actuator.

(MS41-707X shown)

1 Locate and remove the two

jam nuts taped to the

linkage housing, then screw

the nuts to the bottom of the

valve stem (at least 1/4" of

the stem should extend

above the top nut).

2 Tighten the jam nuts

against each other,

using two 5/16"

open-end wrenches.

3 Raise the valve

stem to the full

up position.

6 Rotate the pinion shaft

CW to fully lower the

rack, and then position

the linkage over the

valve stem.

7 Fully thread the

linkage rack onto

the valve stem,

and then engage

the valve mounting

nut in the linkage

adaptor.

9 Rotate the pinion

shaft CCW to raise

the rack and expose

the jam nuts.

10 Tighten the jam

nuts against the

rack, using a 5/16"

open-end wrench

on the lower jam

nut.

4 Loosen the anti-rotation

screw and disengage it

from the slot on the

bottom of the actuator.

Remove the actuator if

necessary.

5 Loosen the shaft

clamp nuts and

remove the actuator

from the linkage.

8 Orient the

linkage on the

valve as desired,

and then tighten

the valve

mounting nut

against the

linkage adaptor,

using a 1-5/8"

open end wrench.

• Install the actuator onto the linkage and 2-way valve, and set-up

the assembly according to Figure 5-1 below.

2 Slide the actuator, "L" side

facing out, onto the linkage's

pinion shaft.

1 Rotate the linkage's pinion shaft to the valve open

position:

• Stem Up Closed Valves - Rotate the pinion shaft

CW to extend the linkage rack to the down position.

3 Align the actuator with the

linkage.

4 Slide anti-rotation screw NYBA-161

half way into the slot on the bottom

of the actuator, and then tighten

the nut on the anti-rotation screw.

direct acting (L) to reverse acting (R), and then

apply power to drive the actuator to the end of

stroke.

d. When finished, return the switch setting to direct acting (L).

Optional: Affix the Open and

Closed labels to the indicator in

the appropriate positions.

6 Lightly finger-tighten the two nuts on the shaft clamp(s), and

then set up the actuator and tighten the shaft clamp(s) as

follows:

For N.C. Operation, Stem Up Closed Valves

a. Power the actuator to the end of stroke

b. Verify that the linkage rack is still in the full down position.

c. Using a 10 mm wrench or socket, torque the nuts equally

on the shaft clamp(s), 8 to 10 lb-ft (11 to 14 N-m). The

actuator is now in the open position, at the end of stroke.

5 Make sure the actuator is in

full contact with the plastic

stand-offs on the linkage.

1 Caution: When used on a VB-9XXX or

similar 1/2" to 1-1/4" (15 mm to 32 mm)

valve body, push the valve stem all the

way down and adjust the rack to get at

least 1/32" (1 mm) clearance above the top

of the packing. Use only 35 lb-in. (16 N-m)

MS40-704X actuators on obsolete valves.

Stem or plug damage may result from

using actuators with higher output torques.

• Apply power to the actuator and check the system's operation for

proper operation, in response to the control signal.

• For electronic hydraulic actuator to DuraDrive actuator, refer to

the wiring diagram on page 7.

• For existing DuraDrive to DuraDrive actuator assembly, refer to

wiring diagrams supplied with your humidifier.

• Install the actuator onto the linkage and 3-way valve, and set-up

the assembly according to Figure 6-1 below.

2 Tip: A 1-5/8" open-end wrench can be used to

measure the amount of rotation (measured between

opposite sides of the slot).

3 Tip:

• MS40-707X, MS40-715X Proportional Control - Change the

reversing switch setting from direct acting (L) to reverse acting (R),

and then apply power to drive the actuator to the end of stroke.

When finished, return the switch setting to direct acting (L).

1 MS40-707X and MS40-715X

actuators are shipped at the

end of stroke, without preload.

6 Apply power to the actuator to rotate it CCW into alignment

with the mounting plate, and then slide anti-rotation screw

NYBA-161 halfway into the slot on the bottom of the

actuator. Tighten the nut on the anti-rotation screw.

Warning: Take care not to pinch your fingers or hand

between the actuator and the mounting plate, when

powering the actuator into alignment.

Caution: When setting the valve preload, power must be

used to position the actuator. Do not manually force the

actuator into the mounting position. If forced, damage to the

pinion shaft or improper close-off may occur.

1-3/8"

3 Align the actuator with the

mounting plate, then rotate it

10° CW. Note that 1-3/8"

movement at the anti-rotation

slot (measured at the anti-

rotation slot's centerline) is

sufficiently equal to 10°.

4 Make sure the actuator is in

full contact with the plastic

stand-offs on the linkage.

5 Holding the actuator at the 10°

position, use a 10 mm wrench or

socket to tighten the two nuts

equally on the shaft clamp, 8 to

10 lb-ft (11 to 14 N-m).

2 Slide the actuator, "L" side

facing out, onto the linkage's

pinion shaft.

over, refer to the wiring diagram on page 7.

• For existing DuraDrive to DuraDrive actuator change-over, refer
