DZ11W Cryogenic Socket Weld Gate Valve Overview The DZ11W Cryogenic Socket Weld Gate Valve is a small-diameter gate valve specifically designed for cryogenic services, featuring a socket weld connection and a forged steel body. It is suitable for ultra-low temperature media such as Liquefied Natural Gas (LNG), liquid oxygen, liquid nitrogen, liquid hydrogen, liquid ammonia, and liquid ethylene.The valve body and key components are manufactured from forged stainless steel (such as F304, F316L) or low-temperature alloy steel (such as A350 LF2). These components undergo deep cryogenic treatment to eliminate residual stresses, ensuring excellent low-temperature toughness and dimensional stability at temperatures as low as -196°C.The valve operates by lifting and lowering the gate to open or close. The length of the extended bonnet is determined based on the operating temperature, positioning the stuffing box away from the cold zone. This design prevents the packing from freezing and mitigates valve stem seizure.This valve is widely used in LNG terminals, air separation units, cryogenic storage and transportation systems, and small-diameter piping systems in the petrochemical industry. It is a critical piece of equipment for achieving reliable shut-off under ultra-low temperature working conditions.DZ11W Cryogenic Socket Weld Gate Valve Product Image

DZ41W Cryogenic Gate Valve Overview The DZ41W Cryogenic Gate Valve is a high-performance gate valve specifically designed for ultra-low temperature media such as Liquefied Natural Gas (LNG), liquid oxygen, liquid nitrogen, liquid hydrogen, liquid ammonia, and liquid ethylene. It features a flanged connection.The valve body and key components are manufactured from low-temperature resistant stainless steel (such as CF8, F304) or low-temperature alloy steel (such as LCB, LC3). These components undergo deep cryogenic treatment to eliminate residual stresses, ensuring excellent low-temperature toughness and dimensional stability at temperatures as low as -196°C.The gate valve operates by lifting and lowering the gate to open or close, making it suitable for fully open or fully closed shut-off applications. The bonnet length is determined based on the operating temperature, utilizing an extended bonnet design. This positions the stuffing box away from the cold zone, preventing the packing from freezing and mitigating valve stem seizure.This valve is widely used in LNG terminals, air separation units, petrochemical low-temperature installations, and energy systems.DZ41W Cryogenic Gate Valve Product Image
