Installation & Maintenance Instructions for
Mark 60 (2½” - 4”) Pressure Regulator
Warning: Jordan Valve Pressure Regulators must only be used, installed and repaired in accordance with these In-
stallation & 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 disassembling
a valve, be sure to release all spring tension.
Please read these instructions carefully!
Your Jordan Valve product will provide you with long,
trouble-free service if it is correctly installed and main-
tained. Spending a few minutes now reading these in-
structions can save hours of trouble and downtime later.
When making repairs, use only genuine Jordan Valve
parts, available for immediate shipment from the factory.
Installation
1. To protect the regulator from grit, scale, thread
chips, and other foreign matter, ALL pipelines
and piping components should be blown out and
thoroughly cleaned before the installation process
begins.
2. Shutoff valves, pressure gauges, and by-pass piping
should be installed as indicated in the 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 0.033 perforated screen is usually
suitable for this purpose. Line strainers are avail-
able 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 com-
pound from getting into pipelines. Pipe sealing
compound should be used sparingly, leaving the
two end threads clean. Jordan uses, and recom-
mends, thread sealer Teflon ribbon.
6. The flow arrow on the valve body must be pointed
in the direction of the flow. Ideally the valve should
be installed in the highest horizontal line of pip-
ing to provide drainage for inlet and outlet piping,
to prevent water hammer, and to obtain faster re-
sponse.
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 pip-
ing 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
recommended.
11. On steam control applications, install a steam trap
with sufficient capacity to drain the coil or condens-
er. 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.
Control Line
A control line must be installed as follows:
1. Connect one end of a 3/8” control line to the 3/8”
NPT tapped opening in the underside of the lower
spring housing.
2. Connect the other end in a straight run of pipe 3 to
5 feet downstream of the valve.
3. DO NOT locate the control line tap in an elbow,
swage, or other changes in configuration of the
pipeline where turbulence or abnormal velocities
may occur.
4. DO NOT locate the control line tap in a vessel, such
as a deaerator located immediately downstream of
the valve instead locate the tap in the pipeline lead-
