Installation & Maintenance Instructions
2-WAY INTERNAL PILOTED-OPERATED SOLENOID VALVES
GENERAL SERVICE - 3/8",1/2" OR 3/4" NPT
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. Series 8210 valves are provided with a general purpose
solenoid enclosure.
Series EF8210 are the same as Series 8210 except they are provided with
an explosionproof/watertight solenoid enclosure.
Notice: Brass valves are not certifi ed as lead-free under the Safe
Water Drinking Act SWDA 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.
OPERATION
Normally Closed: Valve is closed when solenoid is de-energized; open
when energized.
IMPORTANT: Minimum operating pressure differential required
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),
push in knurled cap and rotate stem clockwise 180°. Valve will now
be in the same position as when the solenoid is energized. To disengage
manual operator (close the valve), turn stem counterclockwise 180°.
Push in and rotate
180° clockwise to operate
CAUTION: For valve to operate electrically, manual op-
erator stem must be fully rotated counterclockwise.
Relocation of Manual Operator
Manual operator may be relocated at 90° increments by rotating the
valve bonnet as follows:
WARNING: To prevent the possibility of death,
serious injury or property damage, turn off electrical
power, depressurize valve, and vent fl uid to a safe
area before relocating manual operator.
1.
See separate solenoid installation and maintenance instruction's
and follow instructions to loosen solenoid to allow rotation of en-
closure.
2.
Be sure manual operator stem is fully rotated counterclockwise.
3.
Remove bonnet screws from valve body.
4.
Lift valve bonnet slightly and rotate to desired position. Do not
rotate the diaphragm assembly with the valve bonnet.
5.
Replace bonnet screws and torque in a crisscross manner to 95 ± 10
in-lbs [10,7 ± 1,1 Nm].
6.
Position and tighten solenoid in place,see separate instructions.

NORMALLY CLOSED OPERATION
E242572- 4/14
WARNING: To prevent the possibility of death,
serious injury or property damage, check valve for
proper operation before returning to service.
7.
Test operate valve electrically and manually. Be sure valve can be
test operated without effecting other equipment.
8.
Restore line pressure and electrical power supply to valve.
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.
Future Service Considerations
Provision should be made for performing seat leakage, external leakage,
and operational tests on the valve with a nonhazardous, noncombustible
fl 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.
Mounting
For mounting bracket (optional feature) dimensions, refer to Figure1.
Figure 1. Mounting bracket dimensions
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.
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.
