Product Details

Key Features

Enhanced Safety

Built-in anti-static, anti-blowout stem, fire-safe design, and lockable handle ensure secure operation and prevent accidental valve operation.

Cryogenic-Tested

Each valve is rigorously tested in cryogenic conditions to ensure safe operation in LNG, LPG, and hydrogen applications.

Low Emission Packing

Low-emission packing guarantees leak-free performance, reducing environmental impact and maintaining system integrity.

Extended Stem Design

The extended stem isolates the packing from cryogenic exposure, ensuring long-term sealing and protecting valve components from freezing.

Customizable Materials

Body, seat, stem, ball, and seals can be tailored to meet your specific process needs, optimizing performance across various industrial applications.

Lip Seal + Grease

The lip seal with grease injection ensures superior sealing and smooth operation, even under extreme low-temperature conditions.

Frequently Asked Questions

Cryogenic ball valves are specifically engineered for extremely low-temperature applications, such as LNG, LPG, and liquid nitrogen systems. Unlike standard ball valves, they feature extended stem designs, specialized low-emission packing, and are rigorously tested at cryogenic temperatures to ensure reliable, leak-free performance under conditions that would cause standard valves to fail.

The extended stem design keeps the packing and sealing components away from the cryogenic medium, preventing the packing material from freezing or becoming brittle. This significantly extends the service life of the valve and maintains reliable sealing performance over long operational periods in cold environments.

Cryogenic ball valves are widely used in the LNG (liquefied natural gas), LPG (liquefied petroleum gas), hydrogen energy, air separation, pharmaceutical, and aerospace industries. Any application requiring the control of extremely cold fluids or gases at temperatures as low as -196°C benefits from cryogenic-rated valves.

Yes. The body, seat, stem, ball, and sealing components can all be tailored to match specific process requirements. Common material options include stainless steel, carbon steel, duplex steel, and various PTFE or metal seat configurations, allowing the valve to be optimized for corrosive, high-pressure, or ultra-cold service environments.

The valve incorporates multiple safety mechanisms including an anti-static device to dissipate electrostatic charges, an anti-blowout stem to prevent stem ejection under pressure, a fire-safe design that maintains sealing integrity in the event of a fire, and a lockable handle that prevents unauthorized or accidental valve actuation in critical systems.

Low-emission packing is designed to minimize fugitive emissions — the unintentional release of gases through valve stem seals. By meeting strict emission standards such as ISO 15848 or TA-Luft, these valves help operators reduce their environmental footprint, comply with environmental regulations, and improve workplace safety by preventing the escape of hazardous gases into the atmosphere.
