Liquefied natural gas – The challenge for valves

Due to the existence of large reservoirs of natural gas, many national economies use liquefied natural gas as an alternative to crude oil, which is becoming steadily more expensive and increasingly scarce. Much of this natural gas is transported in liquefied form, known as liquefied natural gas or LNG. To turn natural gas to its liquid form, it must be cooled to below -161 °C. This extremely cold liquid requires special plants and equipment. To effectively shut off pipes, reliable valves are required that are designed to cope with the special physical and chemical properties of this medium. Under the brand AMRI, KSB has been producing butterfly valves for the entire process chain of LNG production for decades.
