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.

Forged Steel Three-Piece Ball Valve Q11F

The forged steel three-piece ball valve is operated by a driving device that rotates the valve stem 90° perpendicular to the passage. It uses a spherical ball with a circular passage as the opening and closing component. Two plastic valve seats are installed on both sides of the ball to seal the leakage between the ball and the valve body. The ball rotates together with the valve stem to open or close the passage.

Ball Valve

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).

American Standard Pressure Self-Sealing Gate Valve PZ40

The gate valve for high-pressure hydrogenation units is a type of gate valve suitable for high-pressure hydrogen environments where the medium is hydrogen gas (containing hydrogen sulfide), hydrogen gas with fuel gas, hydrogen gas with fuel products (containing hydrogen sulfide), etc.
