Asahi BCJ-0082 Single Union Ball Check Valve 3 Inch

Asahi BCJ-0082 Single Union Ball Check Valve 3 Inch is a true-union, non-return valve designed to prevent backflow in thermoplastic piping systems. It uses a freely moving ball that unseats under forward pressure to allow flow and seals against a seat to stop reverse flow, and it can be installed in either vertical or horizontal orientations. The valve family for 3"–4" sizes features body options in PVC, CPVC, PP, and PVDF, with seats available in EPDM, FKM (Viton), or PTFE to match chemical compatibility. The 3" model, part BCJ-0082, is rated up to approximately 100 psi at 70°F, aligning with Asahi/America’s standard performance for single union ball check valves in this size range. Designed for straightforward maintenance, the single-union configuration allows disassembly and inspection without disturbing adjacent piping, simplifying installation and service in demanding water, chemical, and industrial lines. Typical applications include protecting pumps and supply lines from back-siphonage, preventing cross-contamination in process streams, and providing reliable backflow prevention in both utility and manufacturing environments where precise, material-compatible flow control is essential.
