Industrial Valves for LNG Storage & Transportation
LNG Storage & Transportation
Our ultra-low-temperature ball valves (-196°C) integrate patented triple-layer stem sealing and thermal isolation sleeves to prevent icing and gas leaks in LNG terminals and tankers.
Industrial Valves for Aerospace Propulsion Systems
Aerospace Propulsion Systems
Lightweight cryogenic globe valves for liquid oxygen/nitrogen transfer in rocket fueling. Machined from vacuum-treated 316L stainless steel, they achieve ≤0.1% seat leakage (per MSS SP-122) under extreme thermal shocks.
Industrial Valves for Laboratory Cryogenic Research
Laboratory Cryogenic Research
Miniature cryo-valves for liquid helium/hydrogen labs. Electropolished surfaces and bellows seals eliminate particle shedding (meets ISO 15848 CLEAN class).
Industrial Valves for Hydrogen Energy Infrastructure
Hydrogen Energy Infrastructure
-253°C cryogenic valves for liquid hydrogen storage. Double-wall vacuum jacketing and silver-plated gaskets minimize heat ingress, maintaining <30mW/m² thermal flux. Fire-safe API 607 compliance ensures safety in H2 refueling stations and fuel cell plants.
