E-STOP Function:
NFPA 79 requires that push-button emergency stops be of the “self-latching” type,
which means that after an emergency stop actuator is depressed and the contacts
open, the emergency stop device must remain in the actuated position until it is
deliberately reset. If the E-STOP function has been activated, to turn off the gas
supply, you must check for leaks, or reason for activation, before resetting.
Resetting Instructions
Resetting the E-STOP means a person manually intervenes and unlatches the
button by rotating the button to the right.
Tamper Resistant:
The Emergency Stop Button is secure and is not easily removable from the
enclosure.
Safeguarding:
Emergency Stop devices are not a replacement for proper safeguarding or
automatic safety devices. Instead, it should be used as a backup measure. In ad-
dition, the activation of the emergency stop should not impair the effectiveness of
the other safety devices.

OPEN-FRAME, GENERAL PURPOSE, WATERTIGHT/EXPLOSIONPROOF SOLENOIDS
ASCO® solenoid valves with design change letter
“G” or “H’’ in the catalog number ( ex. 821 0G I) 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.
* 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 con-
tact DIN Type 43650 construction (See Figure 6).
OPERATION
Series 8003G/H and 8007G/H - 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,pres-
sure, or weight, must exert a minimum force to overcome re-
sidual magnetism created by the solenoid. Minimum return
force for AC construction is 11 ounces, and 5 ounces for DC
construction.
Series 8202G/H - When the solenoid is energized, the disc
holder assembly seats against the orice. 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 watt-
age. Check front of solenoid for voltage and frequency.
A WARNING: Electrical hazard from the acces-
sibility 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
ACAUTlON: To prevent re or explosion, do not install
solenoid and/or valve where ignition temperature of hazard-
ous 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).
A 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.
Clean periodically depending on service conditions. See
ASCO Series 8600 and 8601 for strainers.

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
A WARNING: To prevent the possibility of death,
serious injury or property damage, turno electrical
power, depressurize solenoid operator and/or valve,
and vent uid to a safe area before servicing.
Cleaning
All solenoid operators and valves should be cleaned
periodically. The time between cleaning will vary depend-
ing 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 lter when cleaning the valve.
Preventive Maintenance
•Keep the medium owing through the solenoid opera-
tor or 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, elas-
tomer 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 op-
erating 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. Replace any worn or damaged parts.
Causes of Improper Operation
• Faulty Control Circuit: Check the electrical system by
energizing the solenoid. A metallic click signies 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 leadwires or
splice connections.
• Burned-Out Solenoid: Check for open-circuited so-
lenoid. Replace if necessary. Check supply voltage; it
must be the same as specied 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. Disconnect conduit, coil leads, and grounding wire.
NOTE: Any optional parts attached to the old solenoid must
be reinstalled on the new solenoid. For 3-way construction,
piping or tubing must be removed from pipe adapter.
2. Disassemble solenoids with optional features as follows:
• Spade or Screw Terminals
Remove terminal connections, grounding screw, ground-
ing 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

DESCRIPTION
Series 8040 valves are 2-way normally closed direct-acting
solenoid valves designed for air or fuel gas service. Valve
bodies are made of rugged aluminum with trim and internal
parts made of steel and stainless steel. Series 8040 valves are
provided with a general purpose solenoid enclosure.
Series 8041 and EF8040 valves are the same as Series
8040 except they are provided with an explosionproof or
explosionproof/watertight solenoid enclosure.
Provisions for Pressure and Seat Leakage Testing
(See Figure 2)
Series 8040G valves are provided with two 1/8” tapped and
plugged holes. One upstream for pressure testing; one down
stream for seat leakage testing. Leakage testing frequency
shall be at least annually in accordance with NFPA-86 or
original equipment manufacturer recommendations. Testing
is also required after valve disassembly and reassembly for
inspection, cleaning or rebuilding.
OPERATION
Normally Closed: Valve is closed when solenoid is de-
energized; open when energized.
NOTE: No minimum operating pressure differential required.
INSTALLATION
Check nameplate for correct catalog number, pressure, voltage,
frequency, and service. Never apply incompatible fl uids or
exceed pressure rating of the valve. Installation and valve
maintenance to be performed by qualifi ed personnel.
Temperature Limitations
For valve ambient and fl uid temperatures, refer to chart below.
Piping
Connect piping to valve according to markings on valve body.
Apply pipe compound sparingly to male pipe threads only. If
applied to valve threads, the compound may enter the valve
and cause operational diffi culty. 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. Valves should be checked for external leakage at piping
connections after installation, see Testing for External Leakage
section.
CAUTION: To avoid damage to the valve body, DO
NOT OVERTIGHTEN PIPE CONNECTIONS. If PTFE
tape, paste, spray or similar lubricant is used, use
extra care when tightening due to reduced friction.
CAUTION: To protect the solenoid valve, install a
strainer or fi lter suitable for the service involved in
the inlet side as close to the valve as possible. Clean
periodically depending on service conditions. See
ASCO Series 8600 and 8601 for strainers.

Testing for External Leakage
WARNING: To prevent the possibility of
severe personal injury or property damage,
extinguish all open fl ames and avoid any type
of sparking or ignition.
1. Block gas fl ow on downstream side of valve.
2. Apply pressure to valve within nameplate rating and
energize solenoid.
3. Apply a soapy solution or a commercially available leak
detecting solution to the pipe connections and check for
bubbles. If the valve has been tested for seat leakage or
disassembled and reassembled for inspecting, cleaning, or
rebuilding apply the solution around solenoid base sub-
assembly, bonnet/body joint and pipe plugs.
4. If leakage exists, depressurize valve and turn off electrical
power supply. Tighten connections as required and retest
following the above steps.
MAINTENANCE
WARNING: To prevent the possibility of
severe personal injury or property damage,
turn off electrical power, depressurize valve,
extinguish all open fl ames, and avoid any
type of sparking or ignition. Vent hazardous
or combustible fl uid to a safe area before
servicing the valve.
NOTE: It is not necessary to remove the valve from the pipeline
for repairs.
Cleaning
All solenoid valves should be cleaned periodically. The time
between cleanings will vary depending on the medium and
service conditions. In general, if the voltage to the coil 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 open or close.
Clean strainer or fi lter when cleaning the valve.
Preventive Maintenance
•Keep the medium fl owing through the valve as free from
dirt and foreign material as possible.
•While in service, the 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. If parts
are worn or damaged, install a complete ASCO Rebuild Kit.
Causes of Improper Operation
•Incorrect Pressure: Check valve pressure. Pressure to
valve must be within range specifi ed on nameplate.
•Excessive Leakage: Disassemble valve and clean all parts.
If parts are worn or damaged, install a complete ASCO
Rebuild Kit.
Valve Disassembly(Refer to Figure 3)
1. Disassemble valve in an orderly fashion using exploded
view for identifi cation and placement of parts.
2. Remove solenoid enclosure. See separate instructions.
3. Unscrew solenoid base sub-assembly from valve bonnet.
4. Remove bonnet screws, valve bonnet, solenoid base gasket,
core assembly (with core spring, rider ring and core guide)
and body gasket from valve body.
5. All parts are now accessible for cleaning or replacement.
If parts are worn or damaged, install a complete ASCO
Rebuild Kit.
Valve Reassembly
1. Lubricate body gasket and solenoid base gasket with DOW
CORNING® 200 Fluid lubricant or an equivalent high-
grade silicone fl uid.
2. Position body gasket and core assembly in valve body.
3. Replace valve bonnet, solenoid base gasket and bonnet
screws.
4. Install bonnet screws and hand thread screws as far as
possible, then torque bonnet screws in a crisscross manner
to 110 ± 10 in-lbs [12 ± 1 Nm].
5. Install solenoid base sub-assembly and torque to 175 ± 25
in-lbs [19,8 ± 2,8 Nm].
6. Install solenoid. See separate instructions.
WARNING: To prevent the possibility of
personal injury or property damage, check
valve for proper operation before returning
to service. Also perform internal seat and
external leakage tests (with a nonhazardous,
noncombustible fl uid if practical).
7. Check valve for external leakage as indicated under the
Piping section, and for internal (seat)leakage as follows.

Testing for Internal (Seat)Leakage
CAUTION: Be sure valve can be tested without
affecting other equipment.
1. Using a 3/16 hex key wrench, remove the 1/8” pipe plug
from the downstream side of the valve body. Then install
suitable test piping (e.g.; two short nipples and an elbow
or tubing) to check for leakage.
2. Block fl ow downstream of valve.
3. Restore electrical power supply and pressurize valve to
nameplate rating.
4. With valve de-energized, immerse end of test piping in
a cup of water for 20-30 seconds and look for bubbles,
which would be indicative of seat leakage. Repeat this
procedure at several progressively lower pressures, down
to approximately 1/4 psi. Between each test, remove cup
of water and operate valve.
5. If seat leakage is detected, turn off electrical power and
depressurize valve. Disassemble and check for proper
placement of parts, or any foreign matter that may have
entered the valve. Clean as necessary, reassemble and re-
test valve for both external and internal leakage.
6. If no seat leakage is detected, remove test piping. Apply a
small amount of Loctite Corporation’s PST Pipe Sealant
567 (or equivalent) to the pipe plug threads. Reinstall the
pipe plug and tighten securely.
7. Test for external leakage as described in Piping section.
8. When maintenance is complete, operate the valve a few
times to be sure of proper operation. A metallic click
indicates the solenoid is operating.
