Valve Coil Resistance
Note: The following coil resistance specifications are at
an ambient temperature of 68°F / 20°C. As valve coil
resistance is sensitive to changes in air temperature, the
coil resistance will typically increase or decrease by 4%
for each 18°F / 10°C that your air temperature increases
or decreases from 68°F / 20°C.
