Ball Float Vent Valves

Ball float vent valves are used in conjunction with extractor vent valves in the Stage I vapor riser or tank vent lines 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.

WARNING: 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.
