A-T Controls OCB-L1-1800-BDB-GE Butterfly Valve

A-T Controls OCB-L1-1800-BDB-GE is an 18-inch, iron lugged butterfly valve built on the OC B-Series platform, designed for flange connections with a lugged body and an ANSI Class 125/150 pressure rating. The OCB designation identifies a ductile iron body (OCB) with a DD stem for sizes 14–24 inches and a keyed stem for larger sizes, offering robust service in demanding piping systems. The valve features a resilient-seated arrangement with a choice of discs: nickel-plated ductile iron or 316 stainless steel (polished option), and seats in EPDM, Buna-N, food-grade EPDM, high-temperature EPDM, Viton, or PTFE to suit various media. The standard stem is 420 stainless steel, with additional materials available, and the design supports a range of trim options from ductile iron to stainless steel, including optional finishes and coatings. The OCB-L1-1800-BDB-GE combines a lug-style body, ductile iron construction, and a modular seating/stem arrangement to deliver tight shutoff and reliable operation in water, wastewater, and general industrial piping where a durable, bolt-on butterfly valve is required.
