Cryogenic Gate Valve

Cryogenic Gate Valve is designed for precise and reliable fluid isolation in extreme low-temperature industrial applications. Engineered with a robust wedge mechanism, this valve provides absolute shut-off control, making it ideal for managing the flow of liquefied natural gas (LNG), liquid nitrogen, liquid oxygen, and other cryogenic fluids down to across a wide range of process conditions.

The cryogenic gate valve ensures superior bubble-tight sealing and stable performance, preventing thermal binding and media entrapment even under high-pressure and extreme thermal cycling environments. Its design features an extended bonnet to position the stem packing away from the freezing fluid, protecting the gland seals from frost formation and extending the valve’s operational life. Widely used in industries such as LNG processing, aerospace, gas separation plants, petrochemical processing, and marine engineering, it plays a critical role in maintaining process efficiency and safety. The valve can be integrated with pneumatic or electric actuators, enabling seamless automation and rapid remote operation in modern cryogenic systems.

Key Features

• Absolute Cryogenic Isolation: Advanced wedge design ensures bubble-tight shut-off and stable fluid containment at temperatures down.

• Extended Bonnet Design: Projects the gland packing away from the cold zone to prevent freezing and ensure dynamic seal integrity.

• Pressure Relief Mechanism: Equipped with internal cavity relief to prevent dangerous over-pressure caused by liquid expansion during ambient temperature boil-off.

• Low Maintenance: Engineered with thermal-expansion-compatible materials to reduce mechanical wear and prevent thermal binding.

• Automation Ready: Compatible with pneumatic, hydraulic, and electric actuators for rapid remote control and emergency shutdown system integration.
