VFB-4612BBC 3 in. 3-Way NPT Characterized Control Valve Body, 100 Cv, Quick-Mount Bracket
Three-way valve body only, piped for mixing or diverting hot or chilled water. Order one of the quick-mount actuators listed below separately; it mounts on the installed bracket. Use this body to build a tri-state or two-position assembly, since premounted assemblies come proportional only. The 3 in. body does not use the standard T pattern of the smaller sizes.
