Compatibility

Valve body for Danfoss self-acting / motorized control assemblies. Combine the VFU 2 DN65 body with a matched actuator (electric AMV / AME, or a matched self-acting unit) sized for the required duty. Select the body by nominal size (DN65), pressure class (PN 16) and flow coefficient (Kvs 50 m³/h); verify actuator stroke 12 mm before ordering.
