ASCO Low Temperature Valves

Winter is Coming – Can Your Valves Withstand Low Ambient Temperatures?

Living in the Midwest, it’s vital to prepare your equipment and operations for the inevitable cold weather that occurs. Part of these preparation include the valves used to control the flow of materials. Many of the standard valves on the market are only rated to 32° F – unfortunately for the Midwest that’s a beautiful winter day and may pose some performance issues for valves without the proper ratings.

Cold weather temperatures can cause performance issues including compromising the integrity of seals, slowed response or dormancy, flexibility of material and more. To ensure your operation is running at optimal efficiency in these low ambient temperatures, ASCO manufactures fluid automation products including valves and cylinders to withstand temperatures down to -40° F.

Why Low Ambient Ratings are Vital to Ensure Reliable Valve Performance

Resiliency and flexibility often deteriorate with low temperatures. When temperatures drop, the elastomers in a valve disc or diaphragm shrink and undergo glass transition which cause a hard, brittleness. These conditions result in seal leakage.

Dormancy can also occur when valves are operated at infrequent intervals. When a valve’s O-ring seals stay in uninterrupted contact for days or months, the seal can adhere against the metal surface of its mating components. When this occurs the valve either does not operate or operates much slower.
