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 qualied service person; continued operation may cause system failure

or a general hazard. Before servicing any valve, disconnect, shut off, or bypass all pressurized uid. 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.

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 Teon 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 ow arrow on the regulator body must be 6.

pointed in the direction of ow. 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 sufcient 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 eld

and must be returned to the factory for repairs.
