Installation & Maintenance Instructions for
Mark 601/602 High Flow 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.
Please read these instructions carefully!
Your Jordan Valve product will provide you with long, trouble-
free service if it is correctly installed and maintained. Spend-
ing a few minutes now reading these instructions can save
hours of trouble and downtime later. When making repairs,
use only genuine Jordan Valve parts, available for immediate
shipment from the factory.
Ideal Installation Schematic
Valve Installation
1. To protect the regulator from grit, scale, thread chips and
other foreign matter, all pipe lines and piping should be
blown out and thoroughly cleaned before the regulator is
installed.
2. Shutoff valves, pressure gauges and bypass piping
should be installed as indicated in the diagram to provide
easier adjustment, operation, and testing.
3. In preparing threaded pipe connections, care should be
exercised to prevent pipe sealing compound from getting
into the pipe lines. Pipe sealing compound should be
used sparingly, leaving the two lead threads clean.
4. A line strainer should be installed on the inlet side of
the regulator to protect it from grit, scale and other
foreign matter. A .033 perforated screen is usually
suitable. Line strainers are available for immediate
shipment from Jordan Valve.
5. Install the regulator in the highest horizontal line of piping
to provide drainage for inlet and outlet piping, to prevent
water hammer and to obtain faster regulation.
6. The flow arrow on the regulator body must be pointed in
the direction of flow. The regulator may be installed
vertically or horizontally without affecting its operation.
7. For best control, 3'-0" straight sections of pipe should be
installed on either side of the regulator.
8. In hot vapor lines, upstream and downstream piping near
the regulator should be insulated to minimize condensa-
tion.
9. If possible, install a relief valve downstream from the
regulator. Set at 15 psi above the control point of the
regulator.
10. Expand the outlet piping at least one pipe size if the
controlled pressure (downstream) is 25% of the inlet
pressure or less. A standard tapered expander connected
to the outlet of the regulator is recommended.
11. Where surges are severe, a piping accumulator is
recommended.
Start-Up
With the inlet and outlet shutoff valves closed:
1.
Throttle the bypass valve so that the pressure to be
controlled is maintained near the set point.
2. Slowly open the inlet shutoff valve.
3. Open the outlet shutoff valve.
4. Slowly close the bypass valve, but do not close it fully
until you are certain that the regulator has control of the
system.
5. To change the controlled pressure, turn the adjusting
screw clockwise to increase pressure, counterclockwise
to decrease pressure.
6. Body and cap bolts should be retightened per torque
procedures after valve reaches operating temperature.
Maintenance
Caution: Make certain that there is no pressure in the valve
before loosening any fittings or joints. The following steps
are recommended:
1.
Close inlet shutoff valve.
2. Allow pressure to bleed off through 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 shutoff
valve, and the valve may be serviced.
