Cryogenic Valve
Cryogenic Ball Valve
Cryogenic ball valve designed for service down to -196°C, with extended bonnet and cold-test certification.
Inquire NowProduct Overview
The cryogenic ball valve is purpose-built for LNG, LPG, liquid nitrogen, and other cryogenic service. The body is forged from low-temperature-rated materials and features an extended bonnet that keeps the packing area away from the chilled process.
Each valve undergoes cryogenic impact testing per BS 6364 / EN 1626 and helium leak testing to ensure performance at the design temperature.
Key Features
- Extended Bonnet: Keeps the packing area above the frost line, preventing cold embrittlement
- -196°C Service: Proven performance in LNG, LPG, LH₂, and LIN service
- Low-Temp Materials: LCC / CF8M / CF3M / 304L — all impact-tested at -196°C
- Cold-Test Certified: Every valve tested per BS 6364 / EN 1626
- Anti-Static Design: Static-conductive ball/stem/spring prevents spark hazards

产品概述
低温球阀专为LNG、LPG、液氮等低温工况设计。阀体采用低温等级锻件，长颈阀盖使填料腔远离冷介质。
每台阀门按BS 6364 / EN 1626标准进行低温冲击试验和氦气检漏，确保在设计温度下性能可靠。
核心特点
- 长颈阀盖： 填料区远离冷介质，避免冷脆
- -196℃工况： LNG、LPG、液氢、液氮工况验证
- 低温材料： LCC/CF8M/CF3M/304L等均通过-196℃冲击试验
- 低温试验认证： 每台阀门按BS 6364/EN 1626测试
- 防静电设计： 球/阀杆/弹簧导电，避免静电火花
