ABSTRACT:
A valve apparatus including a solenoid actuated valve assembly for regulating the flow of fluid vapors from a container. The valve assembly is controlled by electrically energizable circuitry. When the circuitry is completed or closed, the valve assembly will open a passage for a predetermined time period allowing vapors to be exhausted from the container. The circuitry will be closed only when an operator actuated switch is moved by the operator to one of two positions, the inlet port to the container is opened, and after the fluid level in the tank attains a predetermined level.
