Product Description

The Cryogenic Trunnion Mounted Ball Valve with Worm Gear is designed for safe and reliable operation in LNG and low-temperature pipeline systems. The trunnion-supported ball structure ensures low operating torque and stable sealing performance under high pressure conditions.

Featuring an extended cryogenic stem, the valve effectively isolates the packing system from extreme low temperatures, significantly reducing the risk of external leakage. The compact short-body design allows easy installation in space-limited projects while maintaining excellent mechanical strength.

Equipped with a heavy-duty worm gear, the valve offers smooth and controlled manual operation, making it ideal for large-diameter and high-pressure cryogenic applications.

Frequently Asked Questions

What is the minimum operating temperature for this valve?

This valve is specifically designed for ultra-low temperature environments, capable of operating reliably down to -196°C, making it ideal for LNG applications.

Why is an extended stem necessary for cryogenic valves?

The extended stem (cryogenic neck) moves the stem packing away from the cold media. This prevents the packing from freezing and losing its seal, ensuring the valve remains leak-proof and operable.

How does the trunnion mounted design benefit high-pressure systems?

The trunnion structure supports the ball from both the top and bottom. This absorbs the pressure load from the pipeline, which keeps the operating torque low and prevents seat deformation under high pressure.

Is the worm gear operator suitable for large diameter valves?

Yes, the worm gear provides a mechanical advantage that allows for smooth manual operation of large or high-pressure valves that would otherwise be difficult to turn by hand.

What safety features are included in the design?

The valve features an anti-blowout stem design and can be customized with fire-safe and anti-static devices to meet the strict safety requirements of hazardous industrial environments.

Can this valve be used in skid-mounted systems?

Absolutely. The compact short-body design is specifically engineered to save space, making it perfect for modular or skid-mounted pipeline installations.
