Series 291 DC, normally closed solenoid valve, single high flow for LPG applications, 3/4
DESCRIPTION
Series 291 are 2-way normally closed
internal pilot operated single high flow
solenoid valves, designed for LPG fuel
service. The valve body is brass with
stainless steel internal parts.
INSTALLATION
ASCO™ components are intended to be
used only within the technical characteristics
as specified on the nameplate. Changes
to the equipment are only allowed
after consulting the manufacturer or
its representative. Before installation
depressurise the piping system and clean
internally. The equipment may be mounted
in any position. The flow direction and
pipe connection of valves are indicated
on the body.
The pipe connections have to be in
accordance with the size indicated on the
nameplate and fitted accordingly.
CAUTION:
• Reducing the connections may cause
improper operation or malfunctioning.
• For the protection of the equipment install
a strainer or filter suitable for the service
involved in the inlet side as close to the
product as possible.
• If tape, paste, spray or a similar lubricant
is used when tightening, avoid particles
entering the system.
• Use proper tools and locate wrenches as
close as possible to the connection point.
• To avoid damage to the equipment, DO
NOT OVERTIGHTEN pipe connections.
• Do not use valve or solenoid as a lever.
• The pipe connections should not apply any
force, torque or strain to the product.

INSTALLATION AND MAINTENANCE INSTRUCTIONS
ELECTRICAL INSTALLATION/
CONNECTION
In case of electrical connections, they are
only to be made by trained personnel and
have to be in accordance with the local
regulations and standards.
Wiring must comply with local and national
regulations of explosion proof equipment.
The electrical connection is made via a
4 core cable. The green/yellow coloured
lead is the internal ground wire. The
dual winding solenoid types contain two
individual coil windings connected via
(brown) and (black) line leads and a
common neutral lead (blue or grey). The
cable of the solenoid must be static at -40°C
and may be flexed above -8°C. The solenoid
shall be connected to a supply, protected by
fuse capable of extinguishing a prospective
short current.
CAUTION:
• Turn off electrical power supply and
de-energise the electrical circuit and
voltage carrying parts before starting work.
• All electrical screw terminals must be
properly tightened according to the
standards before putting into service.
• Dependent upon the voltage electrical
components must be provided with
an earth connection and satisfy local
regulations and standards.
GROUNDING
To minimise the possibility of personal or
property damage, ensure that grounding of
the coils is maintained through the life of the
valve. The Clip, retaining (item-1) provides
reliable connection between the coil and
the Sol.base sub-assembly if correctly
maintained.

PUTTING INTO SERVICE
Before pressurising the system, first
carry-out an electrical test. In case of
solenoid valves, energise the coil a few
times and check the valve operation.
SERVICE
Most of the solenoid valves are equipped
with coils for continuous duty service.
To prevent the possibility of personal or
property damage do not touch the solenoid
which can become hot under normal
operation conditions. If the solenoid valve is
easily accessible, the installer must provide
protection preventing accidental contact.
SOUND EMISSION
The emission of sound depends on the
application, medium and nature of the
equipment used. The exact determination
of the sound level can only be carried out
by the user having the valve installed in
his system.
MAINTENANCE
M a i n t e n a n c e o f A S C O p r o d u c t s i s
dependent on service conditions. Periodic
cleaning is recommended, the timing of
which will depend on the media and service
conditions. During servicing, components
should be examined for excessive wear. A
complete set of internal parts is available
as a spare parts kit. If a problem occurs
during installation/maintenance or in case
of doubt please contact ASCO or authorised
representatives.

VALVE DISASSEMBLY
Disassemble in an orderly fashion. Pay
careful attention to exploded views provided
for identification of parts.
1. Remove retaining clips and coil
from solenoid base sub-assemblies.
CAUTION : when metal retaining clip
disengages it can spring upwards.
2. Unscrew the solenoid base sub-
assemblies.
3. Remove core/spring assembly and O-ring
bonnet.
4. Remove bonnet screws/washers, valve
bonnet, spring piston,piston assembly, lip
seal, support, O-ring eyelet, eyelet and
body gasket.
5. All parts are now accessible for cleaning
or replacement.
VALVE REASSEMBLY
Reassemble in reverse order of disassembly
paying careful attention to exploded views
provided for identification and placement
of parts.
1. NOTE : Lubricate all gaskets/ O-rings
with high quality silicone grease. Replace
body gasket, O-ring eyelet, eyelet,
support, lip seal, piston assembly, spring
piston, valve bonnet, washers/screw,
O-ring bonnet, core/spring assembly
and solenoid base sub-assemblies.
Torque solenoid base sub-assemblies
and screws according to torque chart.
2. Replace coil and retaining clips.
3. After maintenance, operate the valve a
few times to be sure of proper operation.
