Installation & Maintenance Instructions
2-WAY INTERNAL PILOT OPERATED SOLENOID VALVES
DIAPHRAGM TYPE 3/8", 1/2" AND 3/4" NPT
NORMALLY CLOSED OPERATION - HOT WATER SERVICE
DESCRIPTION
Series 8210 valves with Suffi x "HW" in the catalog number are 2-way,
internal pilot operated solenoid valves designed specifi cally for hot
water service. Standard valves have a General Purpose, NEMA Type
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 certifi ed as lead-free under
the Safe Drinking Water Act SDWA 1417 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" suffi x 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 fi nal selection of the products and
assuring that all performance, safety, and warning requirements
of the applications are met.
OPERATION
Valve is closed when solenoid is de-energized and
Normally Closed:
opens when solenoid is energized
IMPORTANT: Minimum operating pressure differential is 5 PSI.
Manual Operator (Optional)
Valves with Suffi x "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.
Manual Operator Location (Refer to Figures 1 and 2)
Manual operator (when shipped from factory) will be located over the
valve outlet. Manual operator may be relocated at 90° increments
by rotating valve bonnet. Remove bonnet screws (4) and rotate valve
bonnet with solenoid attached to desired position. Replace bonnet
screws (4) and torque in a crisscross manner to 95 ± 10 inch pounds.
If valve is installed in system and is operational, proceed in the
following manner:
WARNING: Depressurize valve and turn off
electrical power supply.
AVERTISSEMENT: Dépressuriser la vanne et
couper l'alimentation électrique.
Remove retaining cap or clip and slip the entire solenoid enclosure

Temperature Limitations (Optional)
For maximum valve ambient and fl uid temperatures, refer to chart
below or as limited by solenoid approvals. See solenoid installation
and maintenance instructions. The temperature limitations listed
are for UL applications. For non UL applications, higher ambient
temperature limitations are available. Consult factory. Check catalog
number on nameplate to determine maximum temperatures.
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 Suffi x "HW" in the catalog number
have a special diaphragm material which is specifi cally
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 suffi xe « HW » dans le
numéro de catalogue sont équipées d'un diaphragme
spécial dont le matièrau est spécifi quement conçu pour
l'utilisation avec de l'eau chaude. Ce matériau peut être
attaqué par l'huile et la graisse. Essuyer les fi letages 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 fi lter 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 fi ttings 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.
