Installation & Maintenance Instructions for Mark 37
Electric Control Valve with MV1005/MV1010 Motors
Warning: Jordan Valve Electric Motor 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,
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 valve from grit, scale, thread chips 1.
and other foreign matter, ALL pipelines and piping
components should be blown out and thoroughly
cleaned before the installation process begins.
Shutoff valves, pressure gauges and by-pass piping
2.
should be installed as indicated in the Ideal Installa-
tion Schematic to provide easier adjustment, opera-
tion, and testing.
A line strainer should be installed on the inlet side
3.
of the regulator to protect it from grit, scale and
other foreign matter. A 0.033 perforated screen is
usually suitable for this purpose. Line strainers are
available from Jordan Valve.
In preparing threaded pipe connections, care
4.
should be exercised to prevent pipe-sealing
compound from getting into the pipelines. Pipe-
sealing compound should be used sparingly,
leaving the two end threads clean. Jordan uses,
and recommends, thread sealer Teflon ribbon.
Install the valve 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
response.
The flow arrow on the regulator body must be
6.
pointed in the direction of the flow. The valve may
be installed in any direction, but damage to the
seating surfaces may occur if installed in a vertical
line with the flow upwards.
To minimize condensation in hot vapor lines and to
7.
protect the motor from excessive heat, piping near
the valve should be insulated.
If possible, install a relief valve downstream from
8.
the regulator. Set at 15 psi above the control point
of the valve.
Expand the outlet piping at least one pipe size if
9.
the downstream pressure is 25% of the inlet pres-
sure or less. A standard tapered expander connect-
ed to the outlet of the valve is recommended.
Where surges are severe, a piping accumulator is
10.
recommended.
For best control, 3’ 0” straight sections of pipe
11.
should be installed on either side of the valve.
Wiring
Caution: Disconnect electrical power supply be-
fore wiring motor into circuit to avoid electrical
shock or possible damage to equipment. Always
disconnect power supply before attempting any
wiring changes.
Make all wiring connections in accordance with local
regulations and national codes. Use No. 18 wire or larger
for all connections to the motor. No. 14 wire should be
used on runs over 500 feet long. When wiring in conduit
with other wires, motor actuator wires must have insula-
tion equal to the other conductors in the conduit run. All
splices are to be made in junction boxes using approved
