Please read these instructions carefully!
Your Jordan Valve product will provide you with long, trouble-
free service if it is correctly installed and maintained. Spending
a few minutes now reading these instructions can save hours of
trouble and downtime later. When making repairs, use only genu-
ine Jordan Valve parts, available for immediate shipment from
the factory.
Ideal Installation Schematic
Preferred Installation
1. To protect the valve from grit, scale, thread chips and other
foreign matter, ALL pipelines and piping components should
be blown out and thoroughly cleaned before the installa-
tion process begins.
2. Shutoff valves, pressure gauges and by-pass piping should
be installed as indicated in the Ideal Installation Schematic
to provide easier adjustment, operation, and testing.
3. A line strainer should be installed on the inlet side of the
valve to protect it from grit, scale and other foreign matter. A
.033 perforated screen is usually suitable for this purpose.
Line strainers are available from Jordan Valve.
4. For best control, 3’-0” straight sections of pipe should be
installed on either side of the valve.
5. In preparing threaded pipe connections, care should be
exercised to prevent pipe-sealing compound from getting
into the pipelines. Pipe-sealing compound should be used

Installation & Maintenance Instructions for
Mark 60 Sliding Gate Pressure Regulators
Warning: Jordan Valve Pressure Regulators 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 leak-
age 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 disassembling a valve, be
sure to release all spring tension.
sparingly, leaving the two end threads clean. Jordan uses,
and recommends, thread sealer Teflon ribbon
6. The flow arrow on the valve body must be pointed in the
direction of flow. Ideally, the valve should be installed in the
highest horizontal line of piping to provide drainage for
inlet and outlet piping, to prevent water hammer, and to
obtain faster response.
7. If possible, install a relief valve downstream from the valve.
Set at 15 psi above the control point of the valve.
8. In hot vapor lines, upstream and downstream piping near
the valve should be insulated to minimize condensation.
9. In gas service, if the control pressure (downstream) is 25%
of the inlet pressure or less, expand the outlet piping at
least one pipe size. A standard tapered expander connected
to the outlet of the valve is recommended.
10. Where surges are severe, a piping accumulator is recom-
mended.
11. On steam control applications, install a steam trap with suf-
ficient capacity to drain the coil or condenser. Be sure to
have a good fall to the trap, and no backpressure. Best
control is maintained if the coil or condenser is kept dry.
Start-Up
1. Fully open the outlet shut-off valve.
2. Slowly open the inlet shut-off valve.
3. Slowly open and close the outlet shut-off valve several times.
This fully strokes the valve to insure satisfactory operation.
4. With the outlet shut-off valve open, slowly screw down the
adjusting screw until the desired pressure is shown on the
outlet pressure gauge.
5. To change the controlled pressure, turn the adjusting screw
clockwise to increase pressure, counterclockwise to de-
crease pressure.
6. Body and cap bolts should be retightened per torque
procedures after valve reaches operating temperature.
Maintenance
Caution: Ensure that the valve is de-pressurized before loos-
ening any fittings or joints. The following steps are recom-
mended before performing any maintenance on the valve:
1. Close the inlet shut-off valve.
2. Allow pressure to bleed off through the downstream piping.
Do not attempt to reverse the flow through the valve by
bleeding pressure from the upstream side of the valve.
3. When the pressure gauges indicate that all pressure has
been removed from the system, close the outlet shut-off
valve. The valve may be removed from the line and ser-
viced.

Valve Seats
A. Disassembly
Jordan Valve Sliding Gate Seats are lapped to light band
flatness. Maintaining such tolerances is of paramount im-
portance for your assurance of excellent control and tight
shutoff. DO NOT use metallic objects in removing the seats.
Care in handling is important.
1. Following the Maintenance procedures to remove the valve
from line.
2. Note scribes (<) on the side of the body (12) and cap (19).
Secure the body flats in a vise. Remove the cap bolts (20)
and two nuts from the studs. Lift the cap straight up.
3. Remove the disc guide (18) by lifting straight up - protect
the lapped surfaces on both sides of the disc guide. Before
removing, check the disc (17) for a stamped arrow. This
arrow points to the "<" on the valve body. (NOTE: discs that
can be rotated 180° without affecting the stroke may not
have arrows.) Lift straight up on the disc (17). Place the disc
on the bench lapped surface facing up. Remove the index
pin (21).
It is imperative that the disc pin (14) assembly is not rotated
when disassembling, cleaning or reassembling, since this
affects the stroke adjustment of the valve.
4. Invert the body and lightly tap on the exterior to remove the
plate (16). Let the plate drop out into your hand, and place
it on the bench with the lapped surface facing up. If the plate
sticks lightly tap on the back of the plate with a soft blunt
object; push the plate (16) out evenly.
5. Clean all the parts , body and cap with solvent. Insert body
and cap bores for damage. If the parts are scarred, do not
attempt to relap them, but return them to the factory for re-
pair or replacement.
6. The vertical sections of the disc guide (18) serve as guides
for the disc (17) while stroking. A 0.005 feeler gauge should
be used to check for clearance between this surface and
the side of the disc. If the clearance is less, clean the guide
surfaces in the disc guide with a fine file.
B. Reassembly
1. Lightly coat the outer ring on the unlapped side or the plate
(16) with anti-seize compound.
2. Place the plate (16) in the body, lapped surface facing the
cap. The index-pin hole should be on the same side of the
body as the "<" on the body. Align the disc pin (14) so that it
is centered in the body bore and that it protrudes through
the center slot in the plate (16). Place the disc (17) on the
plate (16), engaging the disc pin (14). The arrow on the disc
(17) should point to the index-pin hole. Insert the index-pin
(21) in the hole.
3. Coat the outer ring on the side of the disc guide without the
index pin hotel, with a light coating of anti-seize compound.
4. Place the disc guide onto the plate (16), engaging the index-
pin (19). Rotate the assembly slightly until the slot openings
in the disc are parallel to the openings in the plate, and
perpendicular to the stem. Stroking the valve will aide in
this alignment.
5. Align the ">" on the cap (19) with the "<" on the body (12),
and place the cap over the two studs in the body.
6. Install the nuts and cap bolts (20). Tighten uniformly. See
back page for torque requirements and tightening proce-
dures.
Diaphragm Replacement
A. Disassembly
1. Remove all of the compression from the spring (7) by rotat-
ing the adjusting screw (1) counterclockwise until it moves
freely.
(Failure to remove the compression from the spring could
result in personal injury or damage to the valve.)
2. Remove the spring housing bolts (5) and spring housing
(4). Remove the spring (7) and spring seat (6).
3. Remove the diaphragm assembly by rotating counterclock-
wise. The diaphragm assembly consists of the upper dia-
phragm plate (8), diaphragm (9) and lower diaphragm plate
(10).
4. If the diaphragm must be replaced, secure the upper dia-
phragm plate (8) in a vise. A 3/16” face spanner wrench
should be used to remove the lower diaphragm plate (10)
from the assembly.
5. Remove the diaphragm (9) and reassemble in reverse or-
der.
B. Assembly and Stroke Adjustment
1. Note that the valve stroke adjustment is determined by how
far the diaphragm assembly is screwed onto the stem. Screw
the diaphragm assembly onto the stem until the disc pin is
centered in the valve body.
2. Push the diaphragm assembly down against the valve body
and check the orifice alignment of the disc (17) and the
plate (16). The orifices should be fully open and in perfect
alignment.
3. If the orifices are not in perfect alignment, rotate the dia-
phragm assembly counterclockwise to lower the disc, and
clockwise to raise the disc.
4. The total stroke of the Mark 60 is equal to the orifice width
plus 1/32" overlap. Consequently, perfect adjustment is re-
quired for proper operation.
5. When seats are in perfect alignment, Proceed with the
assembly of the spring housing.
6. Place the spring (7) on the upper diaphragm plate (8) and
the spring seat (6) on the spring.
8. If the diaphragm is metal, be sure that the diaphragm is
aligned in the body recess. This recess also aligns the spring
housing (4). Be sure that the bleed hole is facing down-
stream.
9. If the diaphragm is elastomer, make sure that after the seats

If Stroke is Too Short:
To correct, turn the diaphragm assembly
toward you (unthreading it from the stem)
bringing the disc orifices into alignment
with the plate orifices.
If Stroke is Too Long:
To correct, turn the diaphragm assembly
away from you (threading it farther onto the
stem) bringing the disc orifices into alignment
with the plate orifices.
are in perfect alignment that the boltholes are in alignment.
If an adjustment needs to be made to align the bolthole,
make the adjustment by turning the diaphragm assembly
clockwise.
10. Install and tighten the spring housing bolts (5) per the torque
instructions on the back page.
Stroke Adjustment
Disc Pin
1. Remove the disc and the plate, following the procedure
outlined under VALVE SEATS.
2. Remove the diaphragm as outlined under DIAPHRAGM
REPLACEMENT.
3. Holding the disc pin assembly with an open-end wrench,
loosen the locknut (13). The stem (11) can now be
unscrewed from the disc pin (14) and the locknut re-
moved from the stem..
4. Remove the stem (11) upward through the diaphragm
area and the disc pin (14) through the body orifice.
5. Check the condition and clean all parts. Clean the lower
guide hole in the valve body and replace defective parts.
6. Reassemble in reverse order and follow the procedures
outlined under DIAPHRAGM REPLACEMENT and VALVE
SEATS for proper adjustment. When reassembling, thread
the stem (11) fully into the disc pin (14) and then tighten
the locknut (13).
Troubleshooting
If You Experience Erratic Control:
Oversizing causes cycling and hunting, and reduces the
rangeability of the valve. Make certain that your sizing is
correct.
Steam traps downstream may require maintenance.
Safety valve may be defective and need repair.
There may be excessive foreign matter on the seats, and
seats should be removed and cleaned.
Valve stroke may need readjustment.
Valve disc may not be moving freely. Check disc guide
clearance and correct if needed.
If Valve Will Not Operate:
Diaphragm may be ruptured and require replacement.
Adjusting spring may be broken and require replacement.
Spring may be set improperly and require resetting.
Ordering Spare Parts
Use only genuine Jordan Valve parts to keep your valve in
good working order. So 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 Representa-
tive 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 deter-
mined using the following information:
•Model number
•Valve Body size
•Seat Material and Cv rating
•Spring Range or Set Point
•Trim Material
•Part Name - Number and Quantity (see parts list chart).
Note: Without a valve serial
number, any parts ordered
incorrectly are subject to a
minimum 25% restock
charge when returned.
1 The stroke adjustment is made with the spring
housing and adjusting spring removed from
the valve.
2 The valve orifices should be open and in
perfect alignment when the diaphragm
assesmbly is pressed against the valve body
as illustrated.
3 The valve stroke adjustment
is determined by how far the
stem is screwed into the
diaphragm plate. Rotate the
diaphragm assembly to raise
or lower the valve disc.
Unthread the diaphragm
assembly partially to lower
the disc or thread the stem
deeper into the assembly to
raise the disc.
