UltraTech 9928 Self Bailer, XXL

The UltraTech 9928 Self Bailer (XXL) is a high-capacity passive drainage valve engineered to continuously evacuate clean stormwater from containment sumps, bunds, and outdoor storage areas. Operating entirely via mechanical buoyancy, the system allows water to drain freely while automatically sealing off the outlet line the instant an oil sheen or fuel spill is detected. This ensures full regulatory compliance by preventing hydrocarbons from escaping into public drainage infrastructure without requiring electrical power or manual intervention.

Key Features

• Fail-Safe Mechanical Shutoff: Utilizes an internal gravity-assisted buoyancy valve that reacts instantly to hydrocarbons, completely shutting down drainage flow to isolate spilled fluids.

• Continuous Clean Water Drainage: Eliminates the accumulation of rainwater inside outdoor spill pallets, sumps, and secondary containment structures, preserving full systemic retention capacity.

• Corrosion-Resistant Architecture: Constructed from industrial-grade, chemical-resistant polymers engineered to withstand prolonged UV exposure, weathering, and aggressive industrial fluids.

• High-Volume Drainage Capacity: XXL internal plumbing architecture accommodates high-flow discharge rates, preventing pooling during severe or prolonged storm events.

• Integrated Inline Pre-Filtration: Equipped with a debris-retention mesh to prevent silt, leaves, and physical particulates from clogging the sealing mechanism.
