Compatibility

Order a Danfoss AMV/AME linear actuator (15 mm stroke) to drive this VRB 3 body — the body ships without actuator. Three-port valve for mixing (two inlets, one outlet) or diverting service; confirm the flow/mixing mounting orientation. Match DN (DN 40), Kvs (25), PN (PN 16) and the internal-thread connection (Rp 1 1/2Rp 1) against the VRG/VRB data sheet before ordering; external-thread and internal-thread bodies of the same DN are not interchangeable.
