Installation & Maintenance Instructions for
Mark 89 Temperature Regulators (1½” - 2”)
Warning: Jordan Valve Temperature Regulators 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 disassem-
bling a valve, be sure to release all spring tension.
Please read these instructions carefully!
Your Jordan Valve product will provide you with long-term,
trouble-free service if it is correctly installed. Spending a
few minutes of your time reading these instructions now
may save hours of trouble and downtime later.
Installation
To protect the temperature regulator from grit, scale, 1.
thread chips, and other foreign matter, all pipe lines
and piping components should be blown out and
thoroughly cleaned before the valve is installed.
Shutoff valves, pressure gauges, and bypass piping
2.
should be installed as indicated in the diagram to pro-
vide easier adjustment, operation, and testing.
In preparing threaded pipe connections, care should
3.
be taken to prevent pipe sealing compound from get-
ting into the pipe lines. Pipe sealing compound should
be used sparingly, on male threads only, leaving the
two lead threads clean. Jordan uses, and recom-
mends, Seyco #2415 thread sealer Teflon ribbon.
A line strainer should be installed on the inlet side of
4.
the temperature regulator to protect it from grit, scale
and other foreign matter. A 20-mesh Monel screen
is usually suitable. Line strainers are available from
Jordan Valve.
Install the regulator in the highest horizontal line of
5.
piping to provide drainage for inlet and outlet piping,
to prevent water hammer, and to obtain faster regula-
tion.
The flow arrow on the regulator body must be pointed
6.
in the direction of flow. The valve may be installed ver-
tically or horizontally without affecting its operation.
For best control, 3’ 0” straight sections of pipe should
7.
be installed on either side of the valve.
To minimize condensation in hot vapor lines, upstream
8.
and downstream piping near the regulator should be
insulated.
For injection heating applications, the regulator should
9.
be installed above the maximum water level in the
tank, or a check valve should be installed to prevent
water from backing up into the regulator.
For best regulation, the temperature regulator should
10.
be installed as closely as possible to the unit in which
the temperature is being controlled.
On steam control applications, install a steam trap of
11.
sufficient capacity to drain the coil or condenser. Be
sure to have a good fall to the trap, and no back pres-
sure. Best control is obtained when the coil or con-
denser is kept dry.
Bulb Installation
The thermal system is hermetically sealed unit con-
sisting of a sensing bulb, capillary tubing, protective
armor, and actuator assembly. This unit contains the
thermostatic charge that operates the temperature
regulator. Please do not tamper with it. In case the
charge is lost, the thermal system must be replaced
as a complete unit. It is not repairable in the field and
must be returned to the factory for repairs.
Correct Installation 1. - For effective temperature control,
correct installation of the sensing bulb is essential. For
best results, the bulb should be installed at a point of
true representative temperature and where there is
good circulation. A thermometer or other temperature
sensing device (if used) should be placed as close as
possible to the sensing bulb of the regulator.
Handle the capillary and armor carefully so they are
2.
not crushed, kinked, or twisted. A bend of 4½” radius
or larger is recommended.
Horizontal Mounting
3. - when the bulb is to be mounted
horizontally, it must be turned so that the work TOP
(stamped on the adapter) faces upward.
Vertical Mounting
4. - No special precaution is required
when the bulb is mounted vertically pointing down.
Inverted Mounting
5. - A special capillary is required if
the tip of the bulb will be higher than the capillary
