DESCRIPTION

Bulletin 8210’s are 2-way, normally closed internal pilot operated solenoid
valves. Valve bodies and bonnets are of brass construction. Standard
valves have a General Purpose, NEMA Type 1 Solenoid Enclosure.
Bulletin 8211’s are the same as Bulletin 8210’s 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 1, Group
C or D and NEMA Type 9 (E, For G) Hazardous Locations - Class 2,
Groups E, F or G. The Explosion-Proof/Watertight Solenoid Enclosures
are shown on separate sheets of installation and Maintenance
Instructions, Form Numbers V-5380 and V-5391.

OPERATION

Normally Closed: Valve is closed when solenoid is de-energized and
opens when solenoid is energized.

MANUAL OPERATOR

(Optional)

Valves with Suffix ‘MO’ in the 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 3)

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 to
desired position. Replace bonnet screws (4) and torque in a crisscross
manner to 110 ± 10 inch pounds.
If valve is installed in the system and is operational, proceed in the
following manner:

WARNING:

Depressurize valve and turn off electrical

power supply.
1. Remove retaining cap or clip and slip the entire solenoid enclosure off
the solenoid base sub-assembly.

CAUTION:

When metal retaining clip

disengages, it will spring upwards.
2. Remove bonnet screws (4) and rotate valve bonnet to desired position.
3. Replace bonnet screws (4) and torque in a crisscross manner to 110 ±
10 inch pounds. Replace solenoid enclosure and retaining clip or cap.

INSTALLATION

Check nameplate for correct catalog number, pressure, voltage and
service.

TEMPERATURE LIMITATIONS

For maximum valve ambient and fluid temperatures, refer to chart. The
temperature limitations listed are for UL applications. For non-UL
applications, higher ambient and fluid temperature limitations are
available. Consult factory, Check catalog number on nameplate to
determine maximum temperatures.

POSITIONING/MOUNTING

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 (optional
feature) dimensions, refer to Figure 2.

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,
it may enter the valve and cause operational difficulty. Pipe strain should
be avoided by proper support and alignment of piping. When tightening
the 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. See Bulletins 8600, 8601 and 8602 for strainers.

WIRING

Wiring must comply with Local and National Electrical Codes. 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 upwards. Rotate to desired position. Replace
retaining cap or clip before operating.

NOTE:

Alternating Current (A-C) and Direct Current (D-C) solenoids are

built differently. To convert from one to the other, It Is necessary to
change the complete solenoid including the solenoid base sub-assembly
and core assembly.

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 the valve from the
pipe line for repairs.

CLEANING

A periodic cleaning of all solenoid valves is desirable. The time between
cleanings will vary, depending on media and service conditions. In
general, if the voltage to the coil is correct, sluggish valve operation,
excessive leakage or noise will indicate that cleaning is required.

PREVENTIVE MAINTENANCE

1. Keep the medium flowing through the valve as free from dirt and
foreign material as possible.
2. While in service, operate the valve at least once a month to insure
proper opening and closing.
3. 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.
