Asco 8210 series Installation & Maintenance Instructions

Installation & Maintenance Instructions
2-WAY INTERNAL PILOTED-OPERATED SOLENOID VALVES
3/4I and 1I NPT - BRASS CONSTRUCTION
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.
NOTE: No minimum operating pressure differential required.

Manual Operator (optional feature)

Manual operator allows manual operation when desired or during an
electrical power outage.
S For 3/4I NPT Valve Construction - To engage manual
operator (open valve), rotate stem clockwise as far as possible.
Valve will now be in the same position as when the solenoid is
energized. To disengage manual operator, rotate stem
counterclockwise as far as possible.
CAUTION: For valve to operate electrically, manual
operator must be fully disengaged (stem rotated fully
counterclockwise).
S For 1I NPT Valve Construction - To engage manual operator
(open valve), push knobs upward and rotate one quarter turn.
Valve will now be in the same position as when the solenoid is
energized. To disengage manual operator, rotate manual
operator one quarter turn until the manual operator
disengages and returns to its original position.
CAUTION: For valve to operate electrically, manual
operator stem must be fully retracted.

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.

Positioning

Valve must be mounted with solenoid vertical and upright.

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.
CAUTION: To protect the solenoid valve, install a strainer
or filter 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, 8601 and 8602
for strainers.
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 servicing the valve.
NOTE: It is not necessary to remove the valve from the pipeline for
repairs.
