Model 308 Ball Float Vent Valves

EBW’s ball float vent valves are used in conjunction with extractor vent valves in the Stage I vapor riser or tank vent line on underground storage tanks. The ball float vent valve will restrict vapor venting should a full tank condition occur and protects against product mixing and vapor locks due to vent pipe flooding. The bleed hole allows for delivery hose drainage after an overfill.

EBW’s 3” ball float vent valves have been designed to comply with the California Enhanced Vapor Recovery program CP-201 requirements for 3” nominal vapor return piping. When used with an overfill alarm, this valve provides recognized overfill protection for a UST. The valve includes a brass installation cage and will fit all EBW extractor vent fittings.

WARNING: EBW 308 Series float vents should not be used with suction pump systems. For use on gravity drop systems only. Do not use with pump off unloading. Do not use with coaxial Stage I vapor recovery drop tubes.
