Ball valve
American Standard Soft-Sealed Floating Ball Valve Q41F
The ball of the floating ball valve is floating. Under the action of medium pressure, the ball can produce a certain displacement and press tightly against the sealing surface at the outlet end, ensuring the sealing at the outlet end. The structure is simple and the sealing performance is good. The product has passed API 607 fire protection certification.
Ultra-low temperature floating ball valve
Cryogenic ball valves are widely used in liquefied natural gas, liquefied petroleum gas, and other low-temperature industries. They use LIP SEAL sealing rings, and these valves maintain excellent sealing performance in application.
Ultra-low temperature fixed ball valve
Cryogenic ball valves are widely used in liquefied natural gas, liquefied petroleum gas, and other low-temperature industries. They use LIP SEAL sealing rings, and these valves maintain excellent sealing performance in application.
American Standard Low Temperature Soft Sealing Ball Valve DQ347F
This valve is designed for low-temperature conditions (-110 to -50°C), and the extended valve cover meets the minimum extension length of the valve cover neck for non-cold box valves as specified in the GB/T 24925 standard.
Forged Steel High-Temperature Hard Seal Ball Valve
This ball valve is specially designed for the core section of the polysilicon production line—the cold hydrogenation reactor inlet and outlet. It is mainly intended to withstand the extremely harsh working conditions of this section: high temperature and high pressure (with a maximum operating temperature of 560°C), high flow velocity, severe erosion, and a gas-solid two-phase medium containing micron-sized, high-hardness silicon powder.
The gate valve for high-pressure hydrogenation units is a type of gate valve suitable for high-pressure temporary hydrogen conditions with media such as hydrogen gas (containing hydrogen sulfide), hydrogen gas fuel gas, and hydrogen gas fuel products (containing hydrogen sulfide).
