Installation & Maintenance Instructions
2-WAY DIRECT-ACTING SOLENOID VALVES
NORMALLY CLOSED OPERATION
LOW PRESSURE SERVICE
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-acting
solenoid valves designed for low pressure service. Valves are
made of rugged forged brass or stainless steel. Series 8030
valves are provided with a general purpose solenoid
enclosure.
Series EF8030 and 8031 are the same as Series 8030 except
they are provided
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. To engage manual
operator (open the valve). Turn manual operator stem
clockwise. Valve will now be in the same position as when
the solenoid is energized. To disengage manual operator,
turn stem counterclockwise.
CAUTION: Stem must be fully turned (rotated)
counterclockwise before operating valve electrically.
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 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.
