Third-party valves with strokes between 6...20 mm can be motorized, provided they are
"closed with the de-energized" fail-safe mechanism and provided that the necessary
mechanical coupling is available. For SKB32.. and SKB82.. the Y1 signal must be routed
via an additional, freely adjustable end switch (ASC9.3) to limit the stroke.
We recommend that you contact your local Siemens office for the necessary information.
