The primary reason valves freeze is due to pressure drops in the gas flowing through them. The “Joule-Thomson Effect” states that for every 100 psi cut across a valve, the gas experiences a temperature drop of 6-8ºF.

To prevent freezing, some producers wrap their vulnerable valves with insulation and heat tape. While it’s better than nothing, it’s also inefficient and messy.
