and closing pressures Dp
s
, refer to the relevant
valve data sheets.

Valves are phased-out
Third-party valves with strokes between 12…40 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 SKC32.. and SKC82.. actuators 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.
