DESCRIPTION
Catalog Numbers WT8004A1 and EF8004A1 are thermoplastic
encapsulated pull-type solenoids for use with ASCO valves. These
solenoids have three lead wires with one wire for grounding and a
½” male conduit connection. Catalog No. WT8004A1 is designed
to meet Enclosure Type 1 - General Purpose, Types 3 and 3S -
Raintight, Types 4 and 4X - Watertight. Catalog No. EF8004A1
meets Enclosure Types 3 and 3S - Raintight, Types 4 and 4X -
Watertight, Types 6 and 6P - Submersible, Type 7 (A, B, C & D)
Explosionproof Class I, Division 1, Groups A, B, C, & D and Type
9 (E, F, & G) - Dust - Ignitionproof Class II, Division 1, Groups E,
F, & G. (See asterisks [

AC (6.3 W) voltages *
• 24, 100, 110, 120, 110-120, 220, 220-240 @ 50Hz
• 12, 24, 100, 110, 120, 240 @ 60Hz
DC (6.9 W) voltages *
• 6, 12, 24, 28, 48, 100, 120, 240
= Specific voltage is marked on coil
* = Div 1 voltages (UL/CSA, if marked) for EF prefix version. See
accompanying regional requirement cert (example, CCC/NEPSI)
for voltage, Ex protection and temperature limitations (if marked).
OPERATION
When the solenoid is energized, the core assembly is drawn into the
plugnut/core tube sub-assembly. When the solenoid is de-energized,
spring force returns the core assembly to the original position.
Enclosure Types 7 and 9 Only (EF8004A1)*
To prevent re or explosion, do not
install solenoid and/or valve where ignition temperature of
hazardous atmosphere is less than 160 °C. Open circuit before
disassembling. Do not exceed temperature limitations in chart
below. (See asterisk [*] in DESCRIPTION section).
Afin d’éviter le risque de feu
ou d’explosion, ne pas installer la bobine ou l’électrovanne ou
la température d’inflammation en atmosphère explosible est
inferieure à 160 °C. Ouvrez le circuit avant le désassemblage. Ne
pas dépasser les limites de température mentionnées dans le
tableau ci-dessous. (Voir l’astérisque [*] dans la section descriptive).
Temperature Limitations
For maximum ambient/fluid temperatures, refer to chart.
See valve installation and maintenance instructions for valve
temperature limitations.

(See asterisk [*] in DESCRIPTION section)
Positioning
Solenoid may be mounted in any position
Valve Mounting
This solenoid is assembled to a valve that must be rigidly supported
using the valve body mounting provisions.
WARNING
ADVERTISSEMENT
NOTICE: See separate valve installation and maintenance
instructions for information on: Operation, Positioning, Mounting,
Cleaning, Preventive Maintenance, Cause of Improper Operation,
Disassembly and Reassembly of basic valve.
Wiring
To reduce the risk of electrocution, re, or
property damage, wiring must comply with local codes and
the National Electrical Code (NEC).
Pour réduire les risques
d’électrocution, d’incendie ou de dommages matériels, le
câblage doit être conforme aux codes locaux et au NEC.
To facilitate wiring, the solenoid may be rotated 360° in 90°
increments. To rotate solenoid, remove retaining cap (if present)
and four mounting screws, reposition solenoid and replace screws
and retaining cap (if present). Torque screws evenly in a crisscross
manner to 12 in -lbs [1,3 Nm]. Torque retaining cap to 10-12 in - lbs
[1,1-1,3 Nm] using a 21/32” socket.
The solenoid must be grounded with
included grounding wire - do not rely on process pipes for
grounding.
La bobine doit être mise
à la terre avec le l de terre inclus - ne vous ez pas aux
canalisations pour la mise à la terre.
Solenoids have a ½ - 14 NPT male thread. For connection to rigid
metal conduit, metal type NPT electrical fittings should be used or
use ASCO Part Number 264568-001, supplied.
For the explosionproof solenoid (EF8004A1), the female ½ - 14
NPT conduit connector comes preassembled and makes up the full
hazardous location solenoid assembly. Any additional required
electrical fittings must be approved for use in hazardous locations.
Solenoid Temperature
Standard solenoids are designed for continuous duty service. When
the solenoid is energized for a long period, the solenoid becomes
hot and can be touched by hand only for an instant. This is a safe
operating temperature.
MAINTENANCE
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,
Afin d’éviter tout risque de mort,
blessure ou dommage, couper l’alimentation électrique,
dépressuriser la vanne ou l’électrovanne et vidanger le fluide en
zone non dangereuse avant toute maintenance.
Potential Electrostatic Charging Hazard.
Use wet or damp cloth when cleaning coil, non-metallic pilot
or valve body (if applicable).
Risque de charges électrostatiques
en atmosphères explosibles. Utiliser un chion humide
ou mouillé lors du nettoyage de la bobine, Corps de pilote
ou de vanne non métallique (si applicable).
Cleaning (also, see above)
All solenoid operators and valves should be cleaned periodically.
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 or
solenoid operation will occur and the valve or solenoid may fail to
shift. Clean strainer or filter when cleaning the valve.
