ĊSERVICE NOTICEĊ
ASCO solenoid valves with design change letter G" in the catalog number
(example: 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.
DESCRIPTION
Catalog numbers 8016G1 and 8016G2 are epoxy encapsulated pull-type
solenoids. The green solenoid with lead wires and 1/2 conduit 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, & 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 minimum full thread.
Series 8016G 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 3 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
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
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
4 ounces for DC construction.
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.

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
180C. 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).
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.

the complete solenoid including the core and solenoid base sub-assembly,
not just the solenoid. Consult ASCO.
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. The 3/4 bonnet
construction (Figure 1) must be disassembled for installation and installed
with a special wrench adapter.

in customer panel.
2. Position spring washer on opposite side of panel over solenoid base
sub-assembly then replace.
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.
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.
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
1. On solenoids with lead wires disconnect conduit, coil leads, and grounding
wire.
NOTE: Any optional parts attached to the old solenoid must be reinstalled
on the new solenoid.
2. Disassemble solenoids with optional features as follows:
Spade or Screw Terminals
Remove terminal connections, grounding screw, grounding wire, and
terminal block (screw terminal type only).
NOTE: For screw terminals, the socket head screw holding the terminal
block serves as a grounding screw.
Junction Box
Remove conduit and socket head screw (use 5/32 hex key wrench) from
center of junction box. Disconnect junction box from solenoid.
DIN Plug Connector
Remove center screw from DIN plug connector. Disconnect DIN plug
connector from adapter. Remove socket head screw (use 5/32 hex key
wrench), DIN terminal adapter, and gasket from solenoid.
3. Snap off red cap from top of solenoid base sub-assembly.
4. Push down on solenoid. Then using a suitable screwdriver, insert blade in
slot provided between solenoid and nameplate/retainer. Pry up slightly
and push to remove. Then remove solenoid from solenoid base
