Ċ SERVICE NOTICE Ċ
ASCO
solenoid valves with design change letter G" or H" in the catalog
number (ex. 8210G 1) have an epoxy encapsulated ASCO
Red Hat II
solenoid. This solenoid replaces some of the solenoids with metal enclosures
and open-frame constructions. Follow these installation and maintenance
instructions if your valve or operator uses this solenoid.
See separate instructions for basic valve.
DESCRIPTION
Catalog numbers 8003G and 8202G are epoxy encapsulated pull-type
solenoids. The green solenoid with lead wires and 1/2
Ăconduit 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" or EV" 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, & G)-Dust-Ignitionproof Class II,
Division 1 Groups E, F & G. The Class II, Groups F & G Dust Locations
designation is not applicable for solenoids or solenoid valves used for steam
service or when a class H" solenoid is used. See
Temperature Limitations
section for solenoid identification and nameplate/retainer for service. When
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 or 0.63 minimum full thread.
NOTE: Catalog number prefix EV" denotes stainless steel construction.
Catalog numbers 8202G1, 8202G3, 8202G5 and 8202G7 are epoxy
encapsulated push-type, reverse-acting solenoids having the same
enclosure types as previously stated for Catalog numbers 8003G1 and
8003G2.
Series 8003G and 8202G solenoids are available in:
Open-Frame Construction:
The green solenoid may be supplied with
1/4
spade, screw or DIN terminals. (Refer to Figure 4)
Panel Mounted Construction:
These solenoids are specifically designed
to be panel mounted by the customer through a panel having a .062 to .093
maximum wall thickness. Refer to Figure 1 and section on
Installation of
Panel Mounted Solenoid.
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 5).
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 6).
OPERATION
Series 8003G - 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 for AC
construction is 11 ounces, and 5 ounces for DC construction.
Series 8202G - When the solenoid is energized, the disc holder assembly
seats against the orifice. When the solenoid is de-energized , the disc holder
assembly returns.
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, 5 ounces.
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,Ăserious
injury or property damage, install the open - frame
solenoid in an enclosure.

CAUTION: To prevent fire or explosion, do not install solenoid
and/or valve where ignition temperature of hazardous atmosphere is
less than 165
C. On valves used for steam service or when a class
H" solenoid is used, do not install in hazardous atmosphere where
ignition temperature is less than 180
C. See nameplate/retainer for
service.
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 90
C. 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
