solenoid with lead wires and 1/2Ăconduit connection is designed to meet
Enclosure Type 1-General Purpose, Type 2-Dripproof, Types 3 and
3S-Raintight, and Types 4 and 4X-Watertight. The black solenoid on
catalog numbers prefixed EF" is designed to meet 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)-Dust-Ignitionproof Class II, Division 1 Groups
E & F. See Temperature Limitations section for solenoid identification and
nameplate/retainer for service. When Series 8017G is installed just as a
solenoid and not attached to an ASCO valve, the core has a 0.250-28
UNF-2B tapped hole, 0.38 minimum full thread.
Catalog Nos. 8017G1 and 8017G2 are pull type direct-acting solenoids,
while Catalog Nos. 8014G1 and 8014G2 are push type reverse-acting
solenoids.
General purpose solenoids (green) are available in open-frame
construction. This construction may be supplied with 1/4 spade, screw or
DIN terminals (Refer to Figure 2).
Optional Features For Type 1 - General Purpose
Construction Only
Junction Box: This junction box construction meets Enclosure Types
2,3,3S,4, and 4X. Only solenoids with 1/4 spade or screw terminals may
have a junction box. The junction box provides a 1/2 conduit connection,
grounding and spade or screw terminal connections within the junction
box (See Figure 3).
DIN Plug Connector Kit No. K236034:Ă Use this kit only for solenoids with
DIN terminals. The DIN plug connector kit provides a two pole with
grounding contact DIN Type 43650 construction (See Figure 4).
OPERATION
Series 8017G - When the solenoid is energized, the core is drawn into the
solenoid base sub-assembly. IMPORTANT: When the solenoid is
de-energized, the initial return force for the core, whether developed by
spring, pressure, or weight, must exert a minimum force to overcome
residual magnetism created by the solenoid. Minimum return force is 1
pound, 12 ounces.
Series 8014G - When the solenoid is energized, the disc holder assembly
seats against the orifice. IMPORTANT: Initial return force for the disc or
disc holder assembly, whether developed by spring, pressure, or weight, must
exert a minimum force to overcome residual magnetism created by the
solenoid. Minimum return force is 1 pound, 12 ounces. When the solenoid
is de-energized , the disc holder assembly returns.
INSTALLATION
Check nameplate for correct catalog number, service, and wattage. Check
front of solenoid for voltage and frequency.
WARNING: Electrical hazard from the accessibility
of live parts. To prevent the possibility of death,
serious injury or property damage, install the
open-frame solenoid in an enclosure.
FOR BLACK ENCLOSURE TYPES 7 AND 9 ONLY
CAUTION: To prevent fire or explosion, do not install solenoid
and/or valve where ignition temperature of hazardous atmosphere is
less than 180 C.
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 filter, suitable for the service involved in the inlet side as
close to the valve or operator as possible. Clean periodically
depending on service conditions. See ASCO Series 8600, 8601, and
8602 for strainers.
Temperature Limitations
For maximum valve ambient temperatures, refer to chart. The temperature
limitations listed, only indicate maximum application temperatures for field
wiring rated at 90C. Check catalog number prefix and watt rating on
nameplate to determine maximum ambient temperature. See valve
installation and maintenance instructions for maximum fluid temperature.
NOTE: For steam service, refer to Wiring section, Junction Box for
temperature rating of supply wires.

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 solenoid base sub-assembly area.
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. For the watertight and
explosionproof solenoid, electrical fittings must be approved for use in the
approved hazardous locations.
CAUTION: Cryogenic Applications - Solenoid lead wire
insulation should not be subjected to cryogenic temperatures.
Adequate lead wire protection and routing must be provided.

Additional Wiring Instructions For Optional Features:
Open-Frame solenoid with 1/4 spade terminals.
For solenoids supplied with screw terminal connections use #12-18 AWG
stranded copper wire rated at 90C or greater. Torque terminal block screws
to 10 ± 2 in-lbs [1,0 ± 1,2 Nm]. A tapped hole is provided in the solenoid for
grounding, use a #10-32 machine screw. Torque grounding screw to 15 - 20
in-lbs [1,7 - 2,3 Nm]. On solenoids with screw terminals, the socket head
screw holding the terminal block to the solenoid is the grounding screw.
Torque the screw to 15 - 20 in-lbs [1,7 - 2,3 Nm] with a 5/32 hex key
wrench.
Junction Box
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 standard copper wire only to the screw terminals. Within the
junction box use field wire that is rated 90C or greater for connections. For
steam service use 105C rated wire up to 50 psi or use 125C rated wire above
50 psi. After electrical hookup, replace cover gasket, cover, and screws.
Tighten screws evenly in a crisscross manner.
DIN Plug Connector Kit No.K236034
1. The open-frame solenoid is provided with DIN terminals to
accommodate the plug connector kit.
2. Remove center screw from plug connector. Using a small screwdriver,
pry terminal block from connector cover.
3. Use #12-18 AWG stranded copper wire rated at 90C or greater for
connections. Strip wire leads back approximately 1/4 for installation
in socket terminals. The use of wire-end sleeves is also recommended
for these socket terminals. Maximum length of wire-end sleeves to be
approximately 1/4.ĂTinning of the ends of the lead wires is not
recommended.
4. Thread wire through gland nut, gland gasket, washer and connector
cover.
NOTE: Connector housing may be rotated in 90 increments from position
shown for alternate positioning of cable entry.
5. Check DIN connector terminal block for electrical markings. Then
make electrical hookup to terminal block according to markings on it.

6. Position connector gasket on solenoid and install plug connector.
Torque center screw to 5 ± 1 in-lbs [0,6 ± 1,1 Nm].
Installation of Solenoid
Solenoids may be assembled as a complete unit. Tightening is accomplished
by means of a hex flange at the base of the solenoid.
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
WARNING: To prevent the possibility of death,
serious injury or property damage, turn off electrical
power, depressurize solenoid operator and/or valve,
and vent fluid to a safe area before servicing.
Preventive Maintenance
Keep the medium flowing through the solenoid operator or valve as free
from dirt and foreign material as possible.
While in service, the solenoid operator or valve should be operated at least
once a month to insure proper opening and closing.
Depending on the medium and service conditions, periodic inspection of
internal valve parts for damage or excessive wear is recommended.
Thoroughly clean all parts. Replace any worn or damaged parts.
Causes of Improper Operation
Faulty Control Circuit: Check the electrical system by energizing the
solenoid. A metallic click signifies that the solenoid is operating. Absence
of the click indicates loss of power supply. 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 specified on
nameplate/retainer and marked on the solenoid. Check ambient
temperature and check that the core is not jammed.
Low Voltage: Check voltage across the solenoid leads. Voltage must be at
least 85% of rated voltage.
Solenoid Replacement (Refer to Figure 1)
1. Disconnect conduit, coil leads, and grounding wire.
NOTE: Any optional parts attached to the old solenoid must be reinstalled
on the new solenoid. For removal or assembly of optional parts, see
Figure 2, 3 or 4.
2. Snap off red cap from top of solenoid base sub-assembly.
3. Push down on solenoid. Then using a suitable screwdriver, insert blade
between solenoid spacer and nameplate/retainer. Pry up slightly and
push to remove.
4. Remove solenoid spacer and solenoid from solenoid base
sub-assembly.
5. Reassemble in reverse order of disassembly. Use exploded views for
identification and placement of parts.
Disassembly and Reassembly of Solenoids
1. Remove solenoid, see Solenoid Replacement.
2. Remove spring washer from solenoid base sub-assembly.
3. Unscrew solenoid base sub-assembly from valve body. For Series
8014G solenoids a special wrench adapter for the solenoid base
sub-assembly is supplied in the ASCO Rebuild Kit. For wrench
adapter only, order Wrench Kit No. K218950.
4. Remove internal solenoid parts for cleaning or replacement. Use
exploded views for identification and placement of parts.
5. If the solenoid is part of a valve, refer to basic valve installation and
maintenance instructions for further disassembly.
6. Reassemble in reverse order of disassembly. Use exploded views for
identification and placement of parts.
7. Torque solenoid base sub-assembly and adapter to 175±25 in-lbs

ORDERING INFORMATION
FOR ASCO SOLENOIDS
When Ordering Solenoids for ASCO Solenoid Operators or Valves, order
the number stamped on the solenoid. Also specify voltage and frequency.
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. Clean
strainer or filter when cleaning the valve.
