Cryogenic valves feature an extended bonnet to keep the packing away from the extreme cold, specialized materials that don't become brittle, and spring-energized seals to maintain tightness at ultra-low temperatures.
For LNG, ASTM A351 CF8M or A182 F316L are commonly used for their excellent corrosion resistance and low-temperature toughness.
The extended bonnet ensures that the valve stem packing is located above the cryogenic liquid level, preventing the packing from freezing and leaking.
Yes, we provide full documentation including chemical analysis, mechanical tests, and pressure test reports according to API 598 and BS 6364.
Absolutely. We support pressure ratings from 150LB up to 4500LB and PN6 to PN750 to meet your specific project requirements.
PCTFE is generally preferred for extremely low temperatures due to its better sealing properties in cryo-service, while PEEK offers higher mechanical strength and temperature resistance.
