· With valves whose stem is extended in the fully closed position, "direct acting"
means that the valve is fully closed (0%) when positioning signal Y = 0 V resp.
Z = 0 Ω. This applies to all Siemens valves according to "Equipment
combinations" (page 14).
· With valves whose stem is retracted in the fully closed position, "direct acting"
means that the valve is fully open (100%) when positioning signal Y = 0 V resp.
Z = 0 Ω.
