AS-Schneider, an industrial valve specialist, has offered valves and manifolds with a special Arctic Operations Design. These can also be used at very low temperatures as low as minus 55 degrees Celsius without any problem.
While designing the Arctic Operations Valves, AS-Schneider has made sure that it only uses materials that guarantees a safe and reliable operation even at extremely low temperatures. It begins with the selection of a suitable body material: While Austenitic Stainless Steels have a sufficiently high resistance to low temperatures, other materials such as Brass are unsuitable because they are slightly brittle in cold conditions.
AS-Schneider also took care in the design of the stem seals. The specialist relies on PTFE or Graphite for its materials: These are resistant to most process media and also against extreme cold. A leak-free, bubble-tight seal of the Arctic Operations Valves is thus ensured.
AS-Schneider therefore uses a special coating to reduce friction on its Arctic Operations Valves. This is used in the stem thread area and provides for a dry lubricant which maintains the mobility of the valve, even at temperatures down to minus 55 degrees Celsius.
