DESCRIPTION
Series 8210 valves with Suffix “HW” in the catalog number are 2-way,
internal pilot operated solenoid valves designed specifically for hot
water service. Standard valves have a General Purpose, NEMAType
1 Solenoid Enclosure.
Series 8211 valves are the same as Bulletin 8210 valves except the
solenoids are equipped with an enclosure which is designed to meet
NEMA Type 4 - Watertight, NEMA Type 7 (C or D) Hazardous
Locations - Class II, Group E, F or G. Installation and Maintenance
Instructions for this enclosure are provided on I&M Nos. V5380 and
V5391.
Notice: Standard brass valves are not certified as lead-free under
the Safe Drinking WaterAct SDWA1417 and are not intended for
use on drinking water systems. They are intended for control of
water in industrial applications. Consult ASCO for valves rated
for use in potable water applications.
Notice: Constructions with an “LF” suffix meet the lead free-brass
requirement of SDWA 1417 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 and
opens when solenoid is energized
IMPORTANT: Minimum operating pressure differential is 5 PSI.
Manual Operator (Optional)
Valves with Suffix “MO” in catalog number are provided with a
manual operator which allows manual operation when desired or
during an interruption of electrical power. To operate valve manually,
push in knurled cap and rotate clockwise 180°. Disengage manual
operator by rotating knurled cap counterclockwise 180° before
operating electrically.

Positioning/Mounting (Refer to Figures 3 and 4)
This valve is designed to perform properly when mounted in any
position. However, for optimum life and performance, the solenoid
should be mounted vertical and upright so as to reduce the possibility
of foreign matter accumulating in the core tube area. For mounting
bracket dimensions (optional feature) refer to Figures 3 and 4.
Piping
Connect piping to valve according to markings on valve body,
CAUTION: Valves with Suffix “HW” in the catalog number
have a special diaphragm material which is specifically
compounded for hot water service. This material can be
attacked by oil and grease. Wipe the pipe threads clean of
cutting oils and use PTFE tape to seal pipe joints.
ATTENTION: Les vannes avec un suffixe « HW » dans le
numéro de catalogue sont équipées d’un diaphragme
spécial dont le matièrau est spécifiquement conçu pour
l’utilisation avec de l’eau chaude. Ce matériau peut être
attaqué par l’huile et la graisse. Essuyer les filetages des
canalisations pour éliminer les huiles de coupe et utiliser
de l’adhésif PTFE pour sceller les joints des canalisations.
Pipe strain should be avoided by proper support and alignment of
piping. When tightening pipe, do not use valve as a lever. Wrenches
applied to valve body or piping are to be located as close as possible
to connection point.
IMPORTANT: For the protection of the solenoid valve, install a
strainer or filter suitable for the service involved in the inlet side
as close to the valve as possible. Periodic cleaning is required
depending on the service conditions.
Wiring
Wiring must comply with Local and National Electrical Codes.
For valves equipped with an explosion-proof/watertight solenoid
enclosure, the electrical fittings must be approved for use in the
approved hazardous locations. Housings for all solenoids are provided
with connections for 1/2 inch conduit. The general purpose solenoid
enclosure may be rotated to facilitate wiring by removing the retaining
cap or clip.
CAUTION: When metal retaining clip disengages, it will
spring upward. Rotate to desired position. Replace retaining
cap or clip before operating.
ATTENTION: Lorsque le clip de maintien métallique
est dégagé de sa position, il va s’éjecter vers l’extérieur.
Le faites pivoter vers la position souhaitée. Replacer le
capuchon ou clip de maintien avant d’actionner la vanne.

Solenoid Temperature
Standard catalog valves are supplied with coils designed for continuous
duty service. When the solenoid is energized for a long period, the
solenoid enclosure becomes hot and can be touched with the hand only
for an instant. This is a safe operating temperature. Any excessive
heating will be indicated by the smoke and odor of burning coil
insulation.
MAINTENANCE
WARNING: Turn off electrical power supply
and depressurize valve before making repairs. It
is not necessary to remove valve from pipe line
for repairs.
AVERTISSEMENT: Couper l’alimentation
électrique et dépressuriser la vanne avant
d’effectuer des réparations. Il n’est pas
nécessaire de retirer la vanne de la canalisation
pour effectuer des réparations.
Cleaning
Aperiodiccleaningofallsolenoidvalvesisdesirable.Thetimebetween
cleanings will vary, depending on media and service conditions. In
general, if the voltage to the coils is correct, sluggish valve operation,
excessive leakage or noise will indicate that cleaning is required. Be
sure to clean valve strainer or filter when cleaning solenoid valve.
Preventive Maintenance
• Keep the medium flowing through the valve as free from dirt and
foreign material as possible
• While in service, operate valve at least once a month to insure
proper opening and closing.
• Periodic inspection (depending on media and service conditions) of
internal valve parts for damage or excessive wear is recommended.
Thoroughly clean all parts. Replace any parts that are worn or
damaged.
Causes of Improper Operation
• Faulty Control Circuit: Check electrical system by energized
solenoid. A metallic click signifies the solenoid is operating.
Absence of the click indicates loss of power supply. Check for
loose or blown-out fuses, open circuited or grounded coil, broken
lead wires or splice connection.
• Burned-Out Coil: Check for open circuited coil. Replace coil if
necessary.
• Low Voltage: Check voltage across coil leads. Voltage must be at
least 85% of nameplate rating.
• Incorrect Pressure: Check valve pressure. Pressure to valve must be
within range specified on nameplate
• Excessive Leakage: Disassemble valve and clean all parts. Replace
worn or damaged parts with a complete Spare Parts Kit for best
results.
Coil Replacement
Turn off electrical power supply and disconnect coil lead wires.
Proceed in the following manner:
1. Remove retaining cap or clip, nameplate and cover.
