ABSTRACT:
An overflow valve for use in a vapor return line of a vapor recovery system for underground storage fuel tanks. The overflow valve is threadably attached in a main vapor line and communicating with an individual storage fuel tank. A plurality of fingers located around an inner edge of a valve chamber disposed within the overflow valve provide a seat for a spherical float, designed to provide a maximum surface area of the float to be in contact with fluid from an individual storage tank, to provide quick response with which the float moves up and down in the chamber and permitting uninhibited flow of liquid under the float when the float is rising.
