NOTICE: See separate solenoid installation and maintenance
instructions for information on: Wiring, Solenoid Temperature,
Cause of Improper Operation, Coil or Solenoid Replacement.
DESCRIPTION
Series 8210 valves are 2-way normally closed internal pilot-operated
solenoid valves designed for general service. Valves are made of rugged
forged brass or die cast stainless steel. Series 8210 valves are provided
with a general purpose solenoid enclosure. Series EF8210 and 8211 are
the same as Series 8210 except they are provided with an explosionproof
or explosionproof/watertight solenoid enclosure.
Notice: Standard brass valves are not certi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” suf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 nal 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.
IMPORTANT: Minimum operating pressure differential is 5 psi.
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
lever 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 lever counterclockwise until it hits a stop.
To engage, turn lever
clockwise until it
hits a stop.
Partial view of
Manual Operator
CAUTION: For valve to operate electrically, manual
operator lever must be fully rotated counterclockwise.
ATTENTION: An que la vanne fonctionne électriquement,
la commande manuelle doit être complètement tournée dans
le sens inverse des aiguilles d’une montre.
INSTALLATION
Check nameplate for correct catalog number, pressure, voltage,
frequency, and service. Never apply incompatible uids or exceed
pressure rating of the valve. Installation and valve maintenance to be
performed by qualied personnel.
Future Service Considerations
Provision should be made for performing seat leakage, external leakage,
and operational tests on the valve with a nonhazardous, noncombustible
uid after disassembly and reassembly.
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.
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 dif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.
CAUTION: To protect the solenoid valve, install a strainer
or 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.
ATTENTION: An de protéger l’électrovanne ou
l’actionneur, installer une crépine ou un ltre adapté le
plus proche possible en amont de l’électrovanne ou de
l’actionneur. Nettoyer périodiquement le ltre en fonction des
conditions d’utilisation. Se référer aux séries 8600 et 8601
pour les crépines.
MAINTENANCE
WARNING: To prevent the possibility of death,
injury or property damage, turn off electrical power,
depressurize valve, and vent uid to a safe area
before servicing the valve.
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 strainer or lter when cleaning the valve.
Preventive Maintenance
• Keep medium owing through the 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, elastomer 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 specic operating conditions. A successful
operating 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. If parts are worn or damaged, install a
complete rebuild kit.
Causes of Improper Operation
• Incorrect Pressure: Check valve pressure. Pressure to valve must
be within range speci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
