LOW TEMPERATURE PRECAUTIONS
Prior to exposure to freezing temperatures it is highly
recommended the valve be drained.
Water that may be trapped in the body cavity could
freeze and impair the operation of the valve o
damage the valve.
If the valve has a grease fitting in the lower drain,
a sufficient amount of anti-freeze injected into the
body cavity via the lower drain grease fitting will
prevent accumulated water from freezing.
It is also advisable to inject a sufficient amount of
valve lubricant into the grease fittings of the valve
and operator (if present) prior to extended cold
temperatures exposure.
Trapped water should be drained from stem
extensions. Some stem extensions in the field are
equipped with plastic plugs that can be removed to
drain trapped water from the piped extension.
