DESCRIPTION
Series 8222 valves are 2-way normally closed, internal pilot-operated
solenoid valves designed for steam service. Valves are made of rugged
brass or stainless steel with internal parts of stainless steel and elastomers
of ethylene propylene orAflas®. Series 8222 valves may be provided with
a general purpose or explosionproof solenoid enclosure.
Notice: Constructions with an “LF” suffix meet the lead free-brass
requirement of SDWA1417 having 0.25% or less lead (Pb) in brass.
Due to the variety of operating conditions and applications of these
products, the user, through analysis and testing, is solely responsible
for making the final selection of the products and assuring that all
performance, safety, and warning requirements of the applications
are met.
OPERATION
Normally Closed: Valve is closed when solenoid is de-energized; open
when energized.
NOTE: No minimum operating pressure differential required.
Manual Operator (optional feature)
Manual operator allows manual operation when desired or during an
electrical power outage. To engage manual operator (open the valve),
turn stem clockwise until it hits a stop. Valve will now be in the same
position as when the solenoid is energized. To disengage manual
operator (close the valve), turn stem counterclockwise until it hits a stop.
CAUTION: For valve to operate electrically, manual
operator stem must be fully rotated counterclockwise.
ATTENTION: Afinquelavannefonctionneélectriquement,
la commande manuelle doit être complètement tournée dans
le sens inverse des aiguilles d’une montre.
Relocation of Manual Operator
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
relocating manual operator.
AVERTISSEMENT: Pour éviter tout risque de
décès, de blessure grave ou de dégâts matériels,
avant de remettre en place l’opérateur manuel :
couper l’alimentation électrique, dépressuriser la
vanne et purger le fluide dans une zone sûre.
Manual operator may be relocated at 90°increments by rotating the
valve bonnet as follows:
1. See separate solenoid installation and maintenance instructions
and follow instructions to loosen solenoid to allow rotation of
enclosure.
2. Be sure manual operator stem is counterclockwise.
3. Remove bonnet screws from valve body.

5. Replace bonnet screws and torque in a crisscross manner to 50
± 5 in-lbs [5,7 ± 0,6 Nm]. Position and tighten solenoid in place,
see separate instructions.
WARNING: To prevent the possibility of death,
personal injury or property damage, check valve
for proper operation before returning to service.
AVERTISSEMENT : Afin de prévenir le risque
de décès, de graves blessures ou de dommage
matériel, vérifiez le bon fonctionnement de la
vanne avant la remise en service.
6. Test operate valve electrically and manually. Be sure valve can be
test operated without effecting other equipment.
7. Restore line pressure and electrical power supply to valve.
INSTALLATION
Check nameplate for correct catalog number, pressure, voltage, fre-
quency, and service. Never apply incompatible fluids or exceed pres-
sure rating of the valve. Installation and valve maintenance to be per-
formed by qualified personnel.
Future Service Considerations
Provision should be made for performing seat leakage, external leak-
age, and operational tests on the valve with a nonhazardous, noncom-
bustible fluid after disassembly and reassembly.
IMPORTANT: Maximum operating pressure differentials are
based on temperature-related material limitations. Therefore, do
not use valves with a steam source of higher pressure than the
nameplate maximum operating pressure differential. Also do not
use a pressure reducing valve to reduce steam source to rated pres-
sure because this would result in superheated steam of excessive
temperature entering the valve.
Temperature LimitationsAnd Pressure Ratings
For maximum valve ambient and fluid temperatures, refer to chart
below or as limited by solenoid approvals. See solenoid installation and
maintenance instructions.
Positioning
This valve 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.
Mounting
For mounting bracket (optional feature) dimensions, refer to Figure 1.
Piping
Connect piping or tubing to valve according to markings on valve body.
CAUTION:Thisvalveisequippedwithethylenepropylene
elastomers which can be attacked by oils and greases. Wipe
the pipe threads clean of cutting oils.
ATTENTION: Cette vanne est équipée d’élastomères en
éthylène-propylène qui peuvent être attaqués par les huiles
et les graisses. Essuyez les filetages des canalisations pour
éliminer les huiles de coupe.

Apply pipe compound sparingly to male pipe threads only. If applied to
valve threads, the compound may enter the valve and cause operational
difficulty. 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.
CAUTION: To protect the solenoid valve, install a strainer
or filter, 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.
ATTENTION: Afin de protéger l’électrovanne ou
l’actionneur, installer une crépine ou un filtre adapté le
plus proche possible en amont de l’électrovanne ou de
l’actionneur. Nettoyer périodiquement le filtre en fonction
des conditions d’utilisation. Se référer aux séries 8600 et
8601 pour les crépines.
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.
AVERTISSEMENT: Pour éviter tous danger de
mort, de blessure grave ou de dommage matériel,
avant d’intervenir sur la vanne, couper le courant,
purger la vanne dans une zone sécurisée.
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 valve strainer or filter when cleaning the valve.
Preventive Maintenance
• Keep the medium flowing 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.
• Dependingon themediumand serviceconditions,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 specified on nameplate.
• Excessive Leakage: Disassemble valve and clean all parts. If parts
are worn or damaged, install a complete ASCO Rebuild Kit.
