Valves
Flow Control Valves regulate the flow rate. Check valves at the manifold and meter help keep
the meter full of fuel. Manifold and Meter PRVs also help relieve excessive pressure due to
thermal expansion, which could damage parts or make nozzles difficult to open.
Solenoid Valves
Solenoid valves use a solenoid coil to open or close a valve. Valves of this type are either fully
open or fully closed. Servicing consists of replacing the coil, valve body, or board supplying
voltage to the valve. For most Gasboy Commercial units, the voltage of the solenoid must
match whatever voltage is being supplied to the AUTH line input. Gasboy retail and DEF units
use the 115 VAC solenoid. Gasboy Commercial E85 uses a 24 VDC solenoid. If the solenoid
requires replacement, ensure that you replace with the correct voltage solenoid.
Gasboy Atlas units have solenoid valves either built into the manifold, or as components in the
discharge piping line.
Atlas models 8700, 8880, 9152, 9153, 9852, and 9853 have a 1-inch 2-stage solenoid valve
built into the manifold. For service, refer to
All Atlas models that can have internal piping for feeding a satellite use a solenoid valve in the
discharge piping line. These models are 9140, 9840, 9850, and 9152/53 or 9852/53 with a “S”
suffix. For repair or replacement of these valves, read this section.
• Wear eye protection. Residual pressure and entrapped fuel may still be present
and may drain or spray while removing the parts.
• Fire and explosion could result in severe injury or death.
• Test and close the shear valves involved. Shut off power to the unit.
• Remove the parts slowly. Collect fuel in approved containers.
• Clean up all spills promptly.
