Installation & Maintenance Instructions for

Mark 87 Temperature Regulators (1/2” – 6”)

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

To protect the regulator from grit, scale, thread chips, 1.

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

provide easier adjustment, operation, and testing.

In preparing threaded pipe connections, care 3.

should be taken to prevent pipe sealing compound

from getting into the pipe lines. Pipe sealing com-

pound 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

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 valve may be

installed vertically 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.

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.

Where surges are severed, a piping accumulator is 12.

recommended.

Operation

The direct acting pilot valve is normally open, allowing

the upstream pressure to force the main diaphragm

down to open the main valve seats. As the process

temperature approaches the desired setting, the uid

in the bulb vaporizes, creating the necessary pressure

on the pilot diaphragm to throttle the pilot valve toward

the closed position. This starves the pressure supply

to the main diaphragm and the lower spring beings to

close the main valve. The reverse acting pilot is normally

closed, and opens on an increase in temperature.
