Designed for mobile storage tanks and fuel trailers, the DN50 (2") GO Fill Rollover Vent provides vital atmospheric relief while safeguarding your bulk liquid payload during transit.
Engineered to allow tanks to freely breathe during filling and decanting operations, this heavy-duty dual-action vent prevents vacuum collapse and pressure build-up without liquid splash-out on uneven roads.
Crucially, the valve incorporates an automatic rollover shut-off mechanism that instantly seals the vent port if a trailer or tank tilts or overturns—preventing catastrophic fuel spills, protecting site safety, and helping fleet operators maintain strict environmental compliance across Australian job sites.
