308 BALL FLOAT
VENT VALVES
The EBW® ball float vent valves are used in conjunction with extractor
vent valves in the Stage I vapour riser or tank vent line on underground
storage tanks. The ball float vent valve will restrict vapour venting
should a full tank condition occur and protects against product mixing
and vapour locks due to vent pipe flooding. The bleed hole allows for
delivery hose drainage after an overfill.
The valve includes a brass installation cage and will fit all EBW® extractor
vent fittings. All ball floats are made of materials fully compatible with
alcohol/gas blends and biofuels (E-85, Biodiesel, B-20).
