API Cryogenic Globe Valve

Key Features of API Cryogenic Globe Valves:

Material Construction:

Made from stainless steel (SS316, SS304L) or other low-temperature alloys to prevent brittleness.

Extended bonnet design to keep the stem seals at ambient temperature, preventing freezing.

API Standards Compliance:

API 602 (for compact steel gate valves) or API 623 (for globe valves) ensures durability and performance.

API 598 for valve inspection and testing.

Cryogenic Sealing:

Uses PTFE, graphite, or metal seals to maintain leak-tight performance in extreme cold.

Fire-safe design (API 607/API 6FA) for safety in flammable environments.

Temperature Range:

Typically rated for -196°C (-320°F) up to +80°C (+176°F) (for LNG, liquid oxygen, nitrogen, etc.).
