Pressure Regulators
Mark 60 Series
Self-Operated Pressure Regulators
The MK60 Sliding Gate Pressure Regulator is used to
regulate the downstream pressure to a predetermined
setpoint. The spring in the Mark 60 holds the sliding
gate seats in their normally open position to allow the
process media to pass through the seats.
The downstream pressure is sensed beneath the diaphragm. As the downstream pressure exceeds the
setpoint, pressure is exerted on the diaphragm which
raises the stem to modulate the disc (the moveable
component on the sliding gate seat set) toward the
closed position. As the seats close, downstream pressure will be reduced to the required setpoint. A decrease in pressure relaxes the spring and diaphragm to
move the seats toward the open position.
This brochure includes the following Series:
MK60: a line of self-operating pressure regulators
designed with Jordan Valves sliding gate seats
MK61: The MK61 features a larger diaphragm than a
MK60QC: The MK60QC features a Quick Change
dome for simple range spring replacements. Ideal
for facilities with multiple pressure reducing applications - stock one valve with several spare springs to
cover a wide range of needs
MK60H: The MK60H features a handwheel that replaces the adjusting screw for easy changes to the
setpoint
MK60HP: Working pressure fully rated to ANSI Class
600 pressures, the HP options permits setpoints as
high as 450 psi
MK60GP: The MK60GP option requires grain processing modification for starch cookers and other
viscous services
MK601/602: The MK601 and MK602 meet higher
capacity requirements than standard regulators
Sliding Gate Trim unique seat design for unsurpassed trim life and accuracy.
Jorcote Seat Coating ceramic composite for liquids, gases and especially steam. Very low friction with
outstanding wear resistance. Steam tested to 1,000,000
cycles and still maintained Class IV leakage.
Jorlon Diaphragm extremely durable, virtually
universally applicable up to 450F, standard 316 SST
diaphragm applicable up to 650F. Tested without failure to over 1,000,000 full stroke cycles. Ideal for
steam, gases and liquids.
Straight-through Flow The flow is straight through
the valve seats and body. Direction of the disc travel
is perpendicular to the flow, not opposed to the direction of the flow. Thus, the flow does not unbalance
the seats. The MK60 can use a wider range of its
stroke to give accurate control; less offset.
Quiet Operation typically 5-10 dB less than conventional globe style regulators. The disc and plate
are always in contact, which eliminates chattering.
Straight-through flow minimizes turbulence. Multiple
orifices in the plate and disc divide the flow stream
into smaller flow components.
Minimum Maintenance The MK60 sliding gate
seats require no special tools for disassembly. The
seats are pre-lapped at the factory and are self-lapping while in operation ensuring a continual tight shutoff.

Notes:
1. Installed Cv is the Failure Cv for Safety Relief Valve Sizing
2. Assumes SST diaphragm, optimal spring range for set point, and minimum flow = 5% of Cv
3.
Indicates valve reaches full Cv before offset is attained
4. Offset: also known as droop, inaccuracy or deviation from setpoint is an inherent characteristic of self-operated regulators. Many
factors affect and determine offset. Spring rate, diaphragm area and stroke length are three key factors. The short stroke of the SLIDING
GATE design helps minimize droop. These tables can be used to estimate performance of the MK60 regulator.

Notes:
1 Double bolting option is required to reach pressures indicated in Brackets [ ].
2 If weld flanges are supplied, use ratings in TE column or flange rating, whichever is less (i.e. ANSI 600/900 flanges or PN64/100
flanges).
3 Consult factory for availability of ANSI/DIN/JIS flanges not indicated above.

M K 60 SELF-OPERATING PRESSURE REGULATORS
The Jorlon Diaphragm - Revolutionary Diaphragm Sets New Standard
Easily retrofitted - Jorlon can be easily retrofitted in the field with no additional parts. For regulators purchased after the
fall of 1991, only the diaphragm needs to be changed to retrofit either SST or elastomer diaphragms.
Chemical Compatibility Jorlon is PTFE based, so it is compatible with most media except fluorinated gases and
halogenated fluorocarbons. Whether the application is steam, process gases or fluids, Jorlon should be your first choice.
High Pressure Limits The MK60HP has been pressure tested well in excess of the maximum allowable pressures of
the valve. For the smaller MK60s 2" (DN50) and below, it is fully rated to ANSI 300 Class pressure of 720 psi (50 bar) @
100F (38C). While the material itself is vital in achieving these higher pressures, the design of the Sliding Gate regulator (MK60) is crucial in permitting this. The outstanding performance is a combination of the material itself and the
unique design of the sliding gate regulator.
Improved Droop Performance A metal diaphragm is much more rigid than an elastomer diaphragm. As such, metal
diaphragms have decreased sensitivity thereby diminishing performance and accuracy in a self operated regulator.
Jorlon will improve droop performance when used instead of a SST diaphragm as its properties are more similar to those
of elastomer materials.
Less Expensive Jorlon is less expensive than many other diaphragm materials, further increasing its customer value.
High Steam Pressure Capability Extensive steam testing of Jorlon in the Mark 60 pressure regulators qualifies this
material for high pressure steam service. For Mark 60s sizes 2" (DN50) and below, you may install Jorlon in saturated
steam service up to 405 psi (28 bar) @ 450F (232C). For steam service in larger Mark 60s, Jorlon qualifies up to 125
psi (8,6 bar) saturated steam.
Fast Delivery Rely on our 36 hour delivery with Jorlon as the
diaphragm material.
Extremely Long Life Under 300 psi air, Jorlon surpasses
1,000,000 full stroke cycles without failure. The harshest test
was on 450F saturated steam, where Jorlon exceeded the cycle
count for stainless steel by over 150 times - the test was
stopped and the Jorlon diaphragm had yet to fail.
Lower Cost of Ownership Less droop provides more accuracy,
improving efficiency and productivity. Extremely long life results
in more production up-time, fewer spare parts expenses and less
repair labor.

MK60/0707/10K/AB
Jordan Valve offers a full range of pressure regulators in addition to the Mark 60 Self-Operated
Pressure Regulator.
Mark 62 Internally Piloted Pressure Regulators
The Mark 62 is a specialty valve designed for critical application regulation in locations
where space is limited. Small and lightweight in design, the Mark 62 valve provides the
accuracy of a piloted valve with the size, weight and appearance of a single, selfoperated valve.
Mark 63/64 Differential Pressure Regulators
The Mark 63 is designed to maintain a constant differential between the pressure on
the discharge side of the regulator and the signal pressure loaded on the diaphragm.
The Mark 64 provides the same flow capacity as the Mark 63 but with less offset in
controlled pressure due to a larger diaphragm.
Mark 65 Vacuum Regulators
The Mark 65 vacuum regulators control very accurately and shutoff tightly to maintain
the proper vacuum setting. They are used to maintain vacuums at predetermined
settings and to regulate vacuums on evaporators, cookers, grinding fixtures, milking
machines, altitude chambers and other vacuum systems.
Mark 66 Air-Loaded Pressure Regulators
The Mark 66 is a highly accurate and economical air loaded pressure regulator that
provides regulation from a local station or from a remote station. The operation of the
MK66 requires no control spring or pilot. Instead, a static air signal is applied to the top
of the diaphragm to determine the setpoint.
Mark 67 Pilot-Operated Pressure Regulators
The Mark 67 is for critical pressure reducing applications and provides greater accuracy
and lower offset than can be achieved with a self-operated regulator. Because of its
versatility in control, and its accuracy, the Mark 67 can be used in a wide variety of
applications including: controlling the pressure of gaseous oxygen to furnaces at steel
mills, controlling pressure of sealing oil on turbines, and pressure control on steam
mains and distribution lines.
Mark 68G Pressure Regulator
The Mark 68G is a globe-style pressure reducing regulating valve that offers high capacity, accurate regulation, and easy servicing, making it the ideal choice for your industrialgrade pressure reducing applications.
Mark 68HP High Pressure Regulating Valve
The Mark 68HP is designed primarily for high pressure steam service as commonly
found in power plants, refineries, pulp & paper mills, and other high pressure process
applications.
