{"product_id":"ultratech-9937-self-bailer-large","title":"UltraTech 9937 Self Bailer, Large","description":"\u003cp data-path-to-node=\"0\"\u003eThe UltraTech 9937 Self Bailer (Large) is a passive drainage valve engineered to continuously evacuate clean stormwater from outdoor containment sumps, bunds, and secondary containment systems. Operating entirely via mechanical buoyancy, the system allows rainwater to drain freely while automatically sealing off the discharge line the instant an oil sheen or fuel spill is detected. This ensures full environmental compliance by preventing hydrocarbons from escaping into public drainage infrastructure without requiring electrical power or manual oversight.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"1\"\u003eKey Features\u003c\/h3\u003e\n\u003cul data-path-to-node=\"2\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"2,0,0\"\u003eFail-Safe Mechanical Shutoff:\u003c\/b\u003e Utilizes an internal gravity-assisted buoyancy valve that reacts instantly to hydrocarbons, completely shutting down drainage flow to isolate spilled fluids.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,1,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"2,1,0\"\u003eContinuous Clean Water Drainage:\u003c\/b\u003e Eliminates the accumulation of rainwater inside outdoor spill pallets, sumps, and secondary containment structures, preserving full systemic retention capacity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,2,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"2,2,0\"\u003eCorrosion-Resistant Architecture:\u003c\/b\u003e Constructed from industrial-grade, chemical-resistant polymers engineered to withstand prolonged UV exposure, weathering, and aggressive industrial fluids.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,3,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"2,3,0\"\u003eStandard Industrial Sizing:\u003c\/b\u003e Large internal plumbing architecture accommodates standard flow discharge rates, preventing pooling during typical storm events.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,4,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"2,4,0\"\u003eIntegrated Inline Pre-Filtration:\u003c\/b\u003e Equipped with a debris-retention mesh to prevent silt, leaves, and physical particulates from clogging the sealing mechanism.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable style=\"width: 100%;
