The technical data herein is for general information only. Product suitability should be based solely upon customer’s detailed
knowledge and experience with their application.
Connect piping or tubing to valve according to
markings on valve body. Refer to flow diagrams
in OPERATION section. Apply pipe compound
sparingly to male pipe threads only. If applied to
valve threads the compound may enter the valve
and cause operational difficulty. Avoid pipe
strain by properly supporting and aligning pip-
ing. When tightening the pipe, do not use valve
or solenoid as a lever. Locate wrenches applied
to valve body or piping as close as possible to
connection point.
CAUTION
• To avoid damage to the valve body, DO
NOT OVERTIGHTEN PIPE CONNEC-
TIONS. If TEFLON* tape, paste, spray or
similar lubricant is used, use extra care when
tightening due to reduced friction.
• To protect the solenoid valve, install a
strainer or filter, suitable for the service in-
volved, in the inlet side as close to the valve
as possible. Clean periodically depending
on service conditions.

NOTE: The exhaust and/or pressure lines
may be restricted to control cylinder speed on
4-way (5/2) mode only.
Wiring
Wiring must comply with local codes and the Na-
tional Electrical Code. The open-frame solenoid
may be rotated 360°. The open-frame solenoid
is provided with ¼ inch spade terminals and a
grounding spade terminal connection.
NOTE: Valves can be converted from alter-
nating current (AC) to direct current (DC), or
vice-versa, by changing the coil.
CAUTION
Temperature of external casing of coil can
burn skin.
Solenoid Temperature
Series 63 valves are supplied with coils designed
for continuous duty service. When the solenoid is
energized for a long period, the solenoid coil be-
comes hot and can be touched with the hand only
for an instant. This is a safe operating tempera-
ture. Any excessive heating will be indicated by
the smoke and odor of burning coil insulation.
MAINTENANCE
WARNING
To prevent the possibility of death, serious
injury or property damage, turn off electrical
power and depressurize valve before inspect-
ing or servicing the valve.
Preventive Maintenance
• Prepare and follow a routine inspection
schedule based on the media, environment,
and frequency of use.
• Keep the medium flowing through the valve as
free from dirt and foreign material as possible.
Depending on medium and service conditions,
clean valve strainer or filter as required to keep
the valve free of contamination. In the extreme
case, contamination will cause faulty valve op-
eration and the valve may fail to shift.
• While in service, the valve should be operated at
least once a month to ensure proper operation.
