Installation & Maintenance Instructions for
Mark 44 Adjustable Cam Valve
Warning: Jordan Valve Regulators and Control Valves 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 disassembling
a valve, be sure to release all spring tension.
Please read these instructions carefully!
Your Jordan Valve product will provide you with long, trou-
ble-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 mak-
ing repairs, use only genuine Jordan Valve parts, available
for immediate shipment from the factory.
Installation
To protect the valve from grit, scale, thread chips 1.
and other foreign matter, all pipe lines and piping
should be blown out and thoroughly cleaned before
the valve is installed.
Shut-off 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 exercised to prevent pipe sealing com-
pound from getting into the pipe lines. Pipe sealing
compound should be used sparingly leaving the two
end threads clean. Jordan uses, and recommends,
Teflon tape.
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 for immediate
shipment from Jordan Valve.
The flow arrow on the valve body must be pointed in 5.
the direction of the flow. The valve may be installed
in any position. The motor arm may be located on
either side of the body. Refer to the “Maintenance”
portion for correct bolt torques.
The motor arm position may be adjusted in 30° in-
6.
crements relative to the rocker. Adjust to suit by re-
moving the slotted nut (30) and washer (25). Then
separate the motor arm from the pins in the rocker
(23) and reposition it on the pins to suit. Replace the
parts in reverse order and tighten the nut as tight as
possible, without binding it to the shaft.
Operate the valve within its rated pressure and tem-
7.
perature limits, which are on the valve nameplate,
along with materials of construction.
The rotation of the valve may be clockwise or coun-
8.
terclockwise to open. This is controlled by the ad-
justment of the nineteen (19) set screws (24) on the
top of the rocker. The screws must be adjusted in
progressive steps to cause the rotation of the rocker
to stroke the valve. If too large a difference in ad-
justment between successive screws is attempted
the valve may be difficult or impossible to stroke. It
is not necessary to utilize the full valve stroke. The
adjustability feature allows customizing of the valve
operating characteristic to suit your needs.
The motor arm must be connected to the mecha-
9.
nism that will drive the valve. The motor arm travel is
limited to 72° by two set screws (32) threaded into
the angle bracket (7). Be sure that your mechanism
is adjusted so that it does not try to drive the valve
past the stops and cause damage.
The Jordan MK44 valve is not a tight shut-off device.
10.
Other valve means must be provided to insure flow
shutoff.
