NOTE: These solenoids have an internal non-resetable thermal fuse to
limit solenoid temperature in the event that extraordinary conditions
occur which could cause excessive temperatures. These conditions
include high input voltage, a jammed core, excessive ambient
temperature or a shorted solenoid, etc. This unique feature is a standard
feature only in solenoids with black explosionproof/dust-ignitionproof
enclosures (Types 7 & 9).
CAUTION: To protect the solenoid valve or operator,
install a strainer or lter, suitable for the service involved in
the inlet side as close to the valve or operator as possible.

Positioning
This solenoid is designed to perform properly when mounted in any
position. However, for optimum life and performance, the solenoid
should be mounted vertically and upright to reduce the possibility of
foreign matter accumulating in the cartridge assembly area.
Piping (General Instructions)
On some valve constructions, there is pilot exhaust (from the top of the
solenoid) when the valve shifts. The pilot exhaust may be connected to
the main exhaust if the air or inert gas cannot be exhausted directly to
the atmosphere.
CAUTION: Debris entering 1/8” NPT connection at top
of cartridge assembly may cause valve malfunction. Use
exhaust protector provided when venting to atmosphere
or connect to an exhaust system. The exhaust protector
provides a degree of protection against falling dirt, rain,
sleet, snow and dust. External formation of ice on the exhaust
protector may cause valve malfunction. For this case, an
alternate means of venting is required.
ATTENTION: Des impuretés peuvent pénéter dans la partie
haute de la cartouche via le raccord 1/8” NPTet entraîner
un dysfonctionnement de la vanne. Utiliser le protecteur
d’échappement fourni lorsque vous purgez directement dans
l’atmosphère ou connecter le sur un réseau d’évacuation.
Le protecteur d’échappement fournit une protection contre
la pénétration d’impureté, pluie, neige fondue, neige et
poussière. Une formation externe de glace sur le protecteur
d’échappement peut entraîner un dysfonctionnement de la
vanne. Dans ce cas, un autre moyen de purge est requis.
Connect piping to valve according to markings on valve body. Refer
to ow diagrams provided in OPERATION section of basic valve
installation and maintenance instructions.
CAUTION: To avoid damage or accidental
disengagement of cartridge assembly from valve body,
hold cartridge assembly securely by wrenching ats when
installing or removing piping at 1/8” NPT connection on top
of the solenoid.
ATTENTION: An d’éviter des dommages ou une
extraction accidentelle de la cartouche du corps de la vanne,
maintenir fermement la cartouche par les plats de serrage
lors de l’installation ou de la dépose de la tuyauterie au
niveau du raccord 1/8” NPT dans la partie haute de la bobine.

Apply pipe compound sparingly to male pipe threads only. If applied to
valve threads,the compound may enter the valve and cause operational
diculty. Avoid pipe strain by properly supporting and aligning piping.
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: These solenoid valves are intended for use
on clean dry air or inert gas, ltered to 40 micrometres or
better. The dew point of the media should be at least 10°C
(18°F) below the minimum temperature to which any portion
of the clean air/inert gas system could be exposed to prevent
freezing. If lubricated air is used, the lubricants must be
compatible with Nitrile elastomers. Diester oils may cause
operational problems. Instrument air in compliance with ANSI/
ISA Standard 7.0.01-1996 exceeds the above requirements
and is, therefore, an acceptable media for these valves.
ATTENTION : Ces électrovannes doivent être utilisées
avec de l’air sec, du gaz inerte ou gaz naturel propre, ltré
jusqu’à 40 micromètres ou plus. Le point de rosée du uide
doit être d’au moins 10ºC inférieur à la température minimale
à laquelle toute partie du système d’air/gaz inerte propre
pourrait être exposée, an d’éviter le gel. En cas d’utilisation
d’air lubrié, les lubriants doivent être compatibles
avec le FKM et/ou élastomères nitrile. Les huiles diester
peuvent engendrer des problèmes de fonctionnement. L’air
d’instrumentation conforme à la norme ANSI/ISA 7.0.011996 dépasse les exigences ci-dessus et constitue, par
conséquent, un média acceptable pour ces vannes.
Wiring
Wiring must comply with local codes and the National Electrical Code.
All solenoids supplied with lead wires are provided with a grounding
wire which is green or green with yellow stripes and a 1/2” conduit
connection. To facilitate wiring, the solenoid may be rotated 360°
depending upon basic valve construction. For explosionproof solenoid
version, the conduit lead wires are factory sealed for use in hazardous
locations. The wiring method for Nonincendive Class I, Division 2
locations shall be in accordance with Section 501-4(b) of the National
Electrical Code. The eld circuit may be incendive. Wiring methods
suitable for ordinary locations may not be used for wiring in incendive
circuits.
CAUTION: Excessive conduit strain on solenoid housing
may damage solenoid or cause valve malfunction. Be sure
conduit and additional junction boxes within the conduit run
to the solenoid housing are properly aligned and supported.
ATTENTION: Une contrainte de tube excessive sur le
boîtier de solénoïde peut provoquer l’endommagement du
solénoïde ou un dysfonctionnement de la vanne. Assurezvous que le tube et les boîtes de jonction supplémentaires
utilisés pour raccorder le boîtier du solénoïde sont alignés et
soutenus correcteme nt.
Additional Wiring Instructions For Junction Box (optional
feature)
The junction box is used with spade or screw terminal solenoids only
and is provided with a grounding screw and a 1/2” conduit connection.
Connect #12-18 AWG stranded copper wire to the screw terminals.
Within the junction box use eld wire that is rated 90°C or greater for
connections. After electrical hookup, replace cover gasket, cover and
screws. Tighten screws evenly in a crisscross manner.
MAINTENANCE
WARNING: To prevent the possibility of
death, serious injury or property damage, turn
o electrical power, depressurize solenoid valve
and vent uid to a safe area before servicing.
AVERTISSEMENT: Pour éviter tous danger
de mort, de blessure grave ou de dommage
matériel, avant d’intervenir sur la vanne, couper
le courant, purger la vanne dans une zone
sécurisée.
Cleaning
All solenoid operators and valves should be cleaned periodically. The
time between cleaning will vary depending on medium and service
conditions. In general, if the voltage to the solenoid is correct, sluggish
valve operation, excessive noise or leakage will indicate that cleaning is
required. In the extreme case faulty valve operation will occur and the
valve may fail to shift. Clean strainer or lter when cleaning the valve.
Preventive Maintenance
• Keep medium owing through the valve as free from dirt and foreign
material as possible.
• Periodic exercise of the valve should be considered if ambient or
uid conditions are such that corrosion, elastomer degradation,
uid contamination build up, or other conditions that could impede
solenoid valve shifting are possible. The actual frequency of exercise
necessary will depend on specic operating conditions. A successful
operating history is the best indication of a proper interval between
exercise cycles.
• Depending on the medium and service conditions, periodic
inspection of internal valve parts for damage or excessive wear
is recommended. Thoroughly clean all parts. If parts are worn or
damaged, install a complete rebuild kit.
Causes of Improper Operation
• Faulty Control Circuit: Check the electrical system by energizing
the solenoid. Check for loose or blown fuses, open-circuited or
grounded solenoid, broken lead wires or splice connections.
• Burned-Out Solenoid: Check for open-circuited solenoid. Replace
if necessary. Check supply voltage; it must be the same as specied
on nameplate/retainer and marked on the solenoid.
• Low Voltage: Check voltage across the solenoid leads. Voltage
must be at least 85% of rated voltage.
Solenoid Replacement / Disassembly & Reassembly
1. Disconnect conduit, coil leads, and grounding wire.
2. Remove piping from 1/8” NPT connection on top of solenoid for
3-way construction.
CAUTION: To avoid damage or accidental
disengagement of cartridge assembly from valve body,
hold cartridge assembly securely by wrenching ats when
installing or removing piping at top of solenoid.
ATTENTION: An d’éviter des dommages ou une
extraction accidentelle de la cartouche du corps de la vanne,
maintenir fermement la cartouche par les plats de serrage
lors de l’installation ou de la dépose de la tuyauterie au
niveau du raccord 1/8” NPT dans la partie haute de la bobine.
3. Push down on solenoid. Then using a suitable screwdriver, insert
blade between solenoid and nameplate/retainer. Pry up slightly and
push to remove nameplate/retainer.
4. Slip solenoid and spring washer o cartridge assembly.
5. Unscrew cartridge assembly from valve body and remove orice
gasket and cartridge gasket.
