Order a Danfoss AMV/AME linear actuator (15 mm stroke) to drive this VRG 2 body — the body ships without actuator. Two-port throttling valve. Match DN (DN 32), Kvs (16), PN (PN 16) and the external-thread connection (G 2) against the VRG/VRB data sheet before ordering; external-thread and internal-thread bodies of the same DN are not interchangeable.
