Compatibility

Order a Danfoss AMV/AME linear actuator (10 mm stroke) to drive this VB 2 body — the body ships without actuator. Flanged body; mate to PN-matched counter-flanges. Confirm DN (DN 32), Kvs (16 m³/h), PN (PN 25) and the actuator stroke/force against the VM 2 / VB 2 data sheet before ordering. The replaceable valve insert (065B2033-2041) and stuffing-box service kit (065B2070) are the field-serviceable parts.
