1. Core safety design
1. Material Processing
● Degreasing and cleaning of all valve parts (residual oil ≤125 mg/m²)
● Oil-free assembly (in accordance with JB/T 12955 standard)
● Copper alloy friction parts (to prevent sparks)
2. Explosion-proof design
● Two-stage anti-static device (resistance <10 ohms)
● Fire-resistant design (passed API 607 test)
● All-metal seal (eliminates the risk of organic fire)
3. Special Flow Channel
● Gradual flow channel design (flow control ≤25 m/s)
● Mirror polishing (Ra≤0.2μm, to prevent particle build-up)
2. Security Features
1. Anti-explosion design
● Friction parts are made of copper-based alloy
● Anti-fly valve stem design
● Oil-free packaging and transportation
2. Medium Purity Guarantee
● Chloride ion content <25 ppm
● Hydrocarbons <50 mg/m²
● Particle Size Control (NAS 1638 Level 6)
3. Operational safety
● Slow opening and closing design (anti-adiabatic compression)
● Explicit opening indication
● Improper actuation interlock device
3. Typical Applications
1. Air Separation Equipment
● Liquid oxygen pump inlet and outlet
● Oxygen Compression System
● Storage Tank Piping
2. Metallurgical industry
● Converter oxygen gun control
● Electric furnace oxygen enrichment system
● Oxygen Path for Continuous Casting Cutting
3. Chemical industry
● Oxidation reaction device
● Wastewater Treatment Aeration
● Medical Oxygen System
