Germany LIK imported female‑thread cryogenic solenoid valve is a 2/2‑way electromagnetic shut‑off valve dedicated for cryogenic service. Valve body adopts 304L /316L ultra‑low‑carbon stainless steel with cryogenic aging treatment. G/NPT female‑thread connection without flanges. Equipped with **extended‑bonnet thermal‑isolation structure** to block upward cold conduction and prevent coil frosting, condensation and short‑circuit burnout. The piston spool is driven by solenoid coil to realize remote on‑off control for cryogenic liquefied media and low‑temperature gas such as liquid nitrogen, liquid oxygen, liquid argon, LNG and liquid CO₂. Two structures available: direct‑acting type supports zero‑pressure & vacuum start‑up; pilot‑operated piston type for large‑bore high‑pressure cryogenic pipelines. Solve typical failures of ordinary valves under‑196℃ such as seal cold‑brittleness, spool cold‑locking and external leakage. Dedicated automatic actuator for air‑separation equipment, cryogenic storage tanks and deep‑cold test systems。
