Installation & Maintenance Instructions for
Mark 801/802 Temperature Regulators
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 disas-
sembling 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.
Ideal Installation
Preferred Installation
To protect the temperature regulator from grit, scale, 1.
chips, and other foreign matter, all pipe lines and pip-
ing components should be blown out and thoroughly
cleaned before the temperature regulator is installed.
Shutoff valves, pressure gauges, and bypass piping
2.
should be installed as indicated in the Ideal Installa-
tion Schematic to provide easier adjustment, opera-
tion, 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, leaving the two lead threads clean.
Jordan uses, and recommends, Seyco #2415 thread
sealer Teflon ribbon.
A line strainer should be installed on the inlet side of
4.
the regulator to protect it from grit, scale and other
foreign matter. A 0.033 perforated 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 pip-
ing to prevent water hammer, and to obtain faster
regulation.
The flow arrow on the regulator body must be
6.
pointed in the direction of flow. The regulator may be
installed vertically or horizontally without affecting its
operation.
For best control, 3’-0” straight sections of pipe
7.
should be installed on either side of the valve.
To minimize condensation in hot vapor lines, up-
8.
stream and downstream piping near the regulator
should be insulated.
For injection heating applications, the regulator
9.
should 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
10.
should be installed as closely as possible to the unit
in which the temperature is being controlled.
On steam control applications, install a steam trap
11.
of sufficient capacity to drain the coil or condenser.
Be sure to have a good fall to the trap, and no back
pressure. Best control is obtained when the coil or
condenser 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.
