In marine engineering, offshore platforms, and seawater systems, valves operate in a unique environment. Seawater, salt spray, high humidity, and continuous operation cycles combine to create a long-term service environment. In this context, a frequently overlooked fact is that the greatest enemy of marine operations is not pressure, but time.

Valves play a vital role in modern production and daily life, serving everything from mild operating conditions to extreme industrial environments. Cryogenic valves are primarily used in applications such as ethylene plants, liquefied natural gas (LNG) facilities, natural gas/LPG/LNG storage tanks and receiving terminals, air separation units, and petrochemical tail-gas separation equipment.
