The EBW 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. All ball floats are made of materials fully compatible with alcohol/gas blends and biofuels (E-85, Biodiesel, B-20).
