Installation & Maintenance Instructions for
Mark 68HP High Pressure Regulators
Warning: Jordan Valve products must only be used, installed, and repaired in accordance with these Installation & 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 maintained. Spending
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.
1. To protect the regulator from grit, scale, thread chips, and
other foreign matter, all pipe lines and piping components
should be blown out and thoroughly cleaned before the regu-
lator is installed.
2. Shutoff valves, pressure gauges, and bypass piping should
be installed as indicated in the Ideal Installation Schematic
to provide easier adjustment, operation and testing.
3. When 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 spar-
ingly, leaving the two lead threads clean. Jordan Valve uses,
and recommends, thread sealer Teflon ribbon.
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 from Jordan Valve.
5. Install the regulator in the highest horizontal line of piping to
provide drainage for the 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 in-
stalled on either side of the regulator.
8. In hot vapor lines, upstream and downstream piping near the
regulator should be insulated to minimize condensation.
9. If possible, install a relief valve downstream from the regula-
tor. Set at 15 psi above the control point of the regulator.
10. For gas service, 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, use a piping accumulator.
12. Operate the regulator within its rated pressure and temperature.
