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.

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 installation process begins.
2. Shutoff valves, pressure gauges and by-pass piping
should be installed as indicated in the Ideal Installa-
tion Schematic to provide easier adjustment, opera-
tion, 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 the 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 flow. Ideally, the valve should be
installed in the highest horizontal line of piping to
provide drainage for inlet and outlet piping, to pre-
vent 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 pip-
ing near the valve should be insulated to minimize
6 condensation.
9. In gas service, if the control pressure (downstream)
R
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.
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 pres-
sure is shown on the outlet pressure gauge.
5. To change the controlled pressure, turn the adjust-
ing screw clockwise to increase pressure, counter-
clockwise to decrease pressure.
6. Body and cap bolts should be retightened per
torque procedures after valve reaches operating
temperature.
