Installation & Maintenance Instructions
SERIES
2--WAY INTERNAL PILOTED-- OPERATED SOLENOID VALVES
8210
NORMALLY CLOSED OPERATION — GENERAL SERVICE
3/8I,1/2I OR 3/4I NPT
8211
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 and 8211 are the same as Series 8210 except they are
provided with an explosionproof or explosionproof/watertight
solenoid enclosure.
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
operator 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 fluid 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 enclosure.
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. Positionand tightensolenoid in place, see separate instructions.
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 fluids or exceed
pressure rating of the valve. Installation and valve maintenance to be
performed by qualified personnel.
Future Service Considerations
Provision should be made for performing seat leakage, external
leakage, and operational tests on the valve with a nonhazardous,
noncombustible fluid after disassembly and reassembly.
Temperature Limitations
For maximum valve ambient and fluid temperatures, refer to chart
below. Check catalog number and watt rating on nameplate.

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 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.
