This heater allows the stem to move freely in
valves that control fluids at temperatures below
32°F (0°C). It reduces ice crystal formation on
the stem which may damage the packing.
Operating Voltage 24 Vac

Heating Output 20 W
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.
