Compatibility & Fitment
Order a Danfoss AMV/AME linear actuator (15 mm stroke) to drive this VRB 2 body — the body ships without actuator. Two-port throttling valve. Match DN (DN 20), Kvs (6.3), PN (PN 16) and the internal-thread connection (Rp 3/4) against the VRG/VRB data sheet before ordering; external-thread and internal-thread bodies of the same DN are not interchangeable.
