Jordan Valve 667M Series Diaphragm Actuator - Manual

I
nstallatIon
The 667M Diaphragm Actuator is usually delivered
mounted on a Jordan Valve valve body. When in-
stalling 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.
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.
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.

Installation & Maintenance Instructions for the
667M Series Diaphragm Actuator
Warning: Jordan Valve Control Valves must only be used, installed and repaired in accordance with these Installa-
tion & Maintenance Instructions. Observe all applicable public and company codes and regulations. In the event
of leakage or other malfunction, call a qualified service person; continued operation may cause system failure or
a general hazard. Before servicing any valve, disconnect, shut off, or bypass all pressurized fluid. Before disassem-
bling a valve, be sure to release all spring tension.
