InstallatIon

Installation & Maintenance Instructions for the

667M Series Diaphragm Actuator

6. Align the indicator disc with the travel side on
the actuator by adjusting the locknuts.

7. Raise the valve plug until the travel disc aligns
with the top of the scale (full travel).

8. Clamp the actuator and valve body stems
between the two stem connector halves. Insert
and tighten both stem connector cap screws.

Note: Avoid clamping the tip of either the valve stem
or the actuator stem in the stem connector. Failure
to completely clamp the stems may strip the threads
and affect proper operation. The length of each stem
clamped in the stem connector should be equal to or
greater than the diameter of that stem.

The 667M Diaphragm Actuator is usually delivered
mounted on a Jordan Valve valve body. When in­stalling the valve body into the pipeline, consult the
instructions for that particular valve body.

Should you have any questions during the installation
procedure, consult your Jordan Valve Representative.

Actuator Mounting

1. Install the stem locknuts onto the valve stem
and place the travel indicator disc onto the
locknuts.

2. If the valve is direct-acting, push the valve
stem down to close the valve. If the valve is
reverse-acting, push the valve stem down to
open the valve.

3. Place the actuator onto the valve bonnet. If
necessary, use a hoist or lift the actuator in
order to slip the yoke locknut over the valve
stem.

4. Screw the yoke locknut onto the bonnet secur­ ing the actuator to the bonnet.

5. Apply required supply pressure to actuator. If
using a 6-30 signal, apply 35 psi. If using a
3-15 signal, apply 20 psi to move the actuator
stem to the top of the travel.

9. Lift the travel indicator disc to the stem
connector and thread the stem locknuts against
the stem connector.

10. Realign the travel indicator scale to show the
valve position.

Loading Connection

1. The loading pressure is connected to the 1/4­ inch NPT connection in the side of the yoke.

2. For the 667M Series Actuator Size 70, re­ move the 1/4-inch bushing in the 1/2-inch NPT
female connection to increase the connection
size if desired. Piping or tubing can be used,
but should be kept as short as possible to
avoid transmission lag in the control signal. If
an accessory is attached to the actuator ensure
that it has been properly secured.

3. If the valve positioner is provided as part of the
original equipment, the loading pressure con­ nection will be made at the Jordan Valve manu­ facturing facility.

4. Check the valve stem travel by cycling the
actuator several times. Ensure that the proper
travel occurs when the correct pressure range
is applied to the diaphragm.

5. If the valve stem travel or pressure range is in
correct, refer to the “Adjustments” section of this
manual.

Do not place the valve in service if it is not responding
properly to diaphragm loading pressure changes.

1. Loosen and back off the stem locknuts and
indicator disc from the stem connector.

2. Loosen the stem connector cap screws.

Note: Do not use wrenches or other tools directly on
the valve stem as this could cause damage to the
stem surface and valve packing.

3. Tighten the locknuts (Keys 14 and 20) and
complete the adjustment by either screwing the
valve stem into the stem connector to lengthen
travel or out of the stem
connector to shorten travel.

4. Cycle the actuator to ensure that the correct
travel has been achieved and repeat the
adjustment if necessary.

5. When the correct travel has been reached
tighten the stem connector cap screws.

6. Raise the travel indicator disc by threading the
stem locknuts against the stem connector.

7. Adjust the travel scale to match the disc.

Spring

For ease of service, ensure that the control valve is locat­ed for easy access and serviceability with room above
for accessibility. Ensure that sufficient room is provided
below should removal of the actuator and valve plug be
necessary.

adjustments

Travel

Refer to the nameplate on the yoke of the actuator for
details on the specific construction and operating range
of the control valve assembly.

The requirements of your specific application will dictate
the spring and diaphragm used in your 667M Actua­tor, and when in service, the actuator should create full
travel of the valve plug when diaphragm pressure is
applied according to the range indicated on the name
plate. Generally, the diaphragm pressure range is 3 to
15 PSI or 6 to 30 PSI, but other ranges may be used.

If the motion during the actuator travel differs from the
travel stamped on the actuator nameplate, adjust ac­cording to the following directions. In order to adjust
the travel of a direct-acting valve, slightly pressure the
actuator to move the valve plug off of the seat. This
reduces the chance of damaging the valve plug or seat
during adjustments.

If the loading pressure range applied to reach the de­sired travel differs from that specified on the nameplate,
a spring adjustment is required.

Check the “Bench Set” pressure range on the nameplate
when the valve contains no pressure and the packing is
loosely inserted in the bonnet. Refer to the “Diaphragm
Pressure” range on the nameplate when the valve is
controlling the specified pressure drop and the packing
is tightened to stop leaks around the stem.

1. Monitor the loading pressure while making
adjustments. Be sure not to exceed the
pressure specifications of either
the loading regulator or the actuator casings.

2. Each actuator spring has a fixed pressure span.
Changing the spring compression shifts the
span up or down to make the valve
travel coincide with the loading pressure range.

Spring Adjustments cont’d

3. To shift the span up, turn the spring adjustor
(Key 11) into the yoke. To shift the span
down, turn the spring adjustor out of the yoke.

For operation of the 667M Diaphragm Actuator the
actuator stem and valve plug stem must move freely in
response to the loading pressure change on the dia­phragm.

maIntenance

Actuator parts are subject to normal wear and tear and
should be inspected regularly. The frequency of in­spection and replacement of parts is dependent on the
severity of operating conditions.

WARNING:
A sudden release of pressure or any uncontrolled
process uid can cause personal injury or damage to
property. Prior to any disassembly, be sure to:

• Isolate the valve from the process,

• Release all process pressure

• Vent the actuator loading pressure, and

• Relieve all spring compression.

Disassembly

Although the following instructions describe how the
667M Diaphragm Actuator can be completely disas­sembled, when inspection or repairs are required, only
disassemble those parts required to accomplish the job.
Key numbers refer to Figures 3 and 4.

1. Bypass the control valve and reduce the loading
pressure to atmospheric.

2. Remove the tubing or piping from the con-
nection in the top of the yoke (Key 9). For top-
loaded construction also remove the piping or
tubing from the connection in the upper
diaphragm casing (Key 7).

3. Thread the spring adjustor (Key 2) off the stem
(Key 3) to remove all spring compression.

4. If necessary remove the actuator from the valve
body by separating the stem connector (Key 21)
