Key Features & Specifications:
Proper material selection to avoid hydrogen embrittlement and special control of the chemical composition to guarantee the valve performance under -253℃ service. These valves are optimized for minimized vaporization and long-term operational reliability. Multiple end connections and structural configurations allow these liquid hydrogen valves to integrate smoothly into hydrogen storage and transfer applications.
l Size Range: ½″ to 6″ (DN15–DN150) Pressure Rating: 150 lb to 600 lb.
l Temperature Range: –253 °C to +120 °C.
l Connection Types: SW (Socket Weld), BW (Butt Weld), RF (Raised Face flange) — compatible with different piping standards.
l Structure / Type: Lifting-type check valve with extended, vacuum-jacketed body to reduce thermal ingress.
l Disc & Closure Mechanism: Guided disc with spring-return ensures quick response and prevents jamming.
l Extended Design: PCTFE-incorporated extended stem minimizes vaporization space and prevents freezing in cryogenic service.
l Sealing & Insulation: Vacuum-jacketed construction improves thermal isolation.
l Applications: Liquid hydrogen tanks, transfer pipelines, cryogenic service lines, hydrogen supply systems where dependable liquid hydrogen valves are required.
