Figure 1. Auxiliary Switch.
ASC1.6 Auxiliary switch
• Sends a signal to indicate that the valve is
in the 0% stroke position.
• The switching point is fixed at the 0%
stroke position.
Switching capacity 24 Vac

Figure 2. Stem Heating Element.
ASZ6.6 The stem heating element prevents
the formation of ice on the stem when the
medium temperature drops below 32°F (0°C).
It is suited for universal use with valves having
a stem or spindle diameter of 10 or 14 mm.
Operating voltage 24 Vac/dc ± 20%
Power consumption ≤ 40 VA/30W
Figure 3. SKB/C Weather Shield.
599-10065 The SKB/C actuator is UL listed to
meet NEMA Type 3R requirements (a degree
of protection against rain, sleet, and damage
from external ice formation) when installed with
this weather shield and outdoor-rated conduit
fittings in the vertical position. See Service Kits
for replacement ultraviolet resistant cable ties.
