The Hastelloy steel ball valve is specifically designed for efficient operation in extremely cold environments. It features a metal valve seat design to ensure reliable sealing, making it an ideal choice for handling liquefied natural gas (LNG) and other cold materials under low-temperature conditions such as liquefied gases. The valve is made from robust forged steel, providing strength and durability that ensures long-term performance even in harsh conditions like LNG plants, receiving stations, vaporization plants, and LNG carriers.
● Cryogenic Design: The valve is designed for low temperature applications to ensure stable and reliable performance when handling liquefied gases and other cold materials at low temperatures.
● Metal-Seated: The metal valve seat is designed to provide a reliable seal at extreme temperatures, ensuring leak-free operation in challenging low temperature conditions.
● Reliable Performance in Hazardous Media: Specially designed to handle hazardous and flammable media, such as liquefied natural gas, ensuring the safety of critical operations.
