NOTICE: See separate solenoid installation and
maintenance instructions for information on: Wiring,
Solenoid Temperature, Cause of Improper Operation, Coil
or Solenoid Replacement.
DESCRIPTION
Series 8030 valves are 2-way normally closed direct lift
solenoid valves designed for low pressure service. Valves are
made of rugged forged brass or stainless steel. Series 8030
valves may be provided with a general purpose/watertight,
open-frame or watertight/explosionproof solenoid.
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. To engage manual
operator (open the valve), turn stem clockwise until it hits
a stop. Valve will now be in the same position as when the
solenoid is energized. To disengage manual operator (close
the valve), turn stem counterclockwise until it hits a stop.
CAUTION: For valve to operate electrically, manual
operator stem must be fully rotated counterclockwise.
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
Valves with design change letter K" or P" within the
catalog number (example: 8030K043) have a maximum fluid
temperature of 180
_
F. Refer to separate solenoid
Installation and Maintenance Instructions for maximum
ambient temperature.
Positioning
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 to reduce
the possibility of foreign matter accumulating in the
solenoid base sub-assembly area.
Mounting
Refer to Figure 1 for mounting bracket (optional feature)
mounting 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 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.
