Ball valve

Stainless Steel Pneumatic Ball Valve Q641F

Purpose: This valve is suitable for pipelines with a nominal pressure ≤1.6/2.5MPa carrying water, steam, oil products, and nitric acid waterproof media, used for opening and closing. Its greatest advantage is rapid opening and closing.

Stainless Steel Worm Gear Flanged Ball Valve Q341F

Purpose: This valve is suitable for pipelines carrying water, steam, oil products, and corrosive media such as nitric acid, used for opening and closing.

Hard-sealed fixed ball valve

Metal hard-sealed fixed ball valves generally adopt a bidirectional sealing structure, possess independent intellectual property rights, and feature resistance to coking, high temperature and high pressure, erosion, wear, and corrosion. They are certified by API607 fire protection standards.

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.
