Compact Short-Body Design
Space-saving structure for skid-mounted or modular systems while maintaining cryogenic integrity.
Worm Gear Operation
Smooth and controlled manual actuation with reduced torque, suitable for frequent operation.
Cryogenic Sealing System
Specialized seat and seal materials accommodate low-temperature contraction for reliable shut-off.
High Safety Design
Anti-blowout stem with optional fire-safe and anti-static devices for critical and hazardous applications.
Product Details
SLVCN 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.
