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.
SERVICE STATION
HARDWARE
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).
