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 genu-
ine Jordan Valve parts, available for immediate shipment from
the factory.
Ideal Installation Schematic
Preferred Installation
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 installa-
tion process begins.
2.
Shutoff valves, pressure gauges and by-pass piping should
be installed as indicated in the Ideal 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
.033 perforated screen is usually suitable for this purpose.
Line strainers are available 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 compound from getting
into the pipelines. Pipe-sealing compound should be used

Installation & Maintenance Instructions for
Mark 60 Sliding Gate 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.
sparingly, leaving the two end threads clean. Jordan uses,
and recommends, 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 prevent 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 piping 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 recom-
mended.
11. On steam control applications, install a steam trap with suf-
ficient capacity to drain the coil or condenser. 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.
Start-Up
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 pressure is shown on the
outlet pressure gauge.
5.
To change the controlled pressure, turn the adjusting screw
clockwise to increase pressure, counterclockwise to de-
crease pressure.
6.
Body and cap bolts should be retightened per torque
procedures after valve reaches operating temperature.
Maintenance
Caution: Ensure that the valve is de-pressurized before loos-
ening any fittings or joints. The following steps are recom-
mended before performing any maintenance on the valve:
1.
Close the inlet shut-off valve.
2.
Allow pressure to bleed off through the 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 shut-off
valve. The valve may be removed from the line and ser-
viced.
