Cytiva, 18575801, Valve, 4-port, 4-way, i.d. 6 mm, 25 mm TC

The Cytiva four-port, four-way valve provides multiple manually selectable flow paths for compatible BPG chromatography systems and associated process fluid lines. A 6 mm internal diameter and 25 mm sanitary clamp interfaces define the connection geometry for this version. The four-way function is different from a simpler two-way switching valve and enables more varied routing configurations during column preparation, loading, or cleaning. Stainless steel and PTFE fluid-contacting components are suited to compatible buffer systems, while the published valve rating is 10 bar. System pressure must remain within the lowest rating of any connected component. Map port positions before operation so sample, buffer, and waste lines cannot be inadvertently cross-connected. Ensure sanitary clamps and gaskets are correctly selected, assembled, and leak-tested. Periodic inspection and cleaning help maintain predictable switching and reduce retained material at changes of process stage.
