Installation & Maintenance Instructions for

Mark 33 Electric Motor Control Valves

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 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

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

Installation

To protect the valve 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 should 3.

be exercised to prevent pipe sealing compound from

getting into the pipe lines. Pipe sealing compound

should be used sparingly, leaving the two lead threads

clean.

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.

Install the valve in the highest horizontal line of pip-5.

ing to provide drainage for inlet and outlet piping, to

prevent water hammer and to obtain faster response.

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

pointed in the direction of ow. The valve may be

installed in any direction, but damage to the seating

surfaces may occur if installed in a vertical line with

the ow 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 the 8.

regulator. Set at 15 psi above the control point of the

valve.

Expand the outlet piping at least one pipe size if the 9.

downstream pressure is 25% of the inlet pressure or

less. A standard tapered expander connected to the

outlet of the valve is recommended.

Where surges are severe, a piping accumulator is 10.

recommended.

For best control, 3’ straight sections of pipe should 11.

be installed on either side of the valve.

Wiring

Caution: Disconnect electrical power supply before

wiring motor into circuit to avoid electrical show or

possible damage to equipment. Always disconnect

power supply before attempting any wiring changes.

See the Motor Manufacturer’s literature, supplied with

the valve, for wiring connections and instructions.
