Hard Back Seat LCB Wafer Butterfly Valve

The LCB wafer butterfly valve is made of cryogenic steel-low-temperature steel  which is a type of steel specifically designed to work in low-temperature environments. Its advantages include:

• Excellent low-temperature toughness: Low-temperature steel can maintain good toughness and strength at extremely low temperatures, allowing it to work normally in extremely cold environments.
• Suitable for low-temperature processes: Low-temperature steel is widely used in low-temperature processes such as liquefied natural gas (LNG) and liquefied petroleum gas (LPG).

However, low temperature steel LCB wafer butterfly valve also has some disadvantages, such as:

• Higher cost: Since low-temperature steel needs to have excellent low-temperature properties and corrosion resistance, its manufacturing cost is usually higher.
• Difficulty in processing: Due to the special performance requirements of low-temperature steel, it may be more difficult to process and requires higher processing and welding processes.
• Poor weldability: Some special types of low-temperature steel may have certain difficulties in welding and require special welding processes and materials.
