DESCRIPTION
🏅 Structural Design:
Integrated PA6 body with conical valve seat + pre-tension spring｜Near-zero forward flow resistance.
Triple fail-safe: 316L anti-corrosion spring + redundant fluoroelastomer seal + dust filter.
🏅 Technical Advantages:
IATF 16949:2016 certified｜Compliant with EU ECE R40 & China IV GB14622-2016.
Quick-connect interfaces (Φ6mm/Φ8mm)｜Fits mainstream motorcycle EVAP systems.
KEY FEATURES
💡 Precision Pressure Control
0.5kPa ultra-low cracking pressure (industry avg. 2kPa) – boosts charcoal canister efficiency by 50%.
Dual-stage seal: primary fluoroelastomer + secondary PTFE guide ring｜Leakage ≤0.003mL/min.
💡 Extreme Environment Durability
30,000-cycle lifespan (industry standard: 10,000)｜Passes -40℃ freeze + 135℃ hot oil cycle tests.
PA6 body withstands 800-hour salt spray (designed for coastal/Middle East high-humidity).
💡 Anti-Clogging Design
Self-cleaning valve seat: automatically removes residue during operation, zero clogging risk.
Low flow resistance: pressure drop <1.5kPa (industry avg. 4kPa)｜Ensures vapour recovery efficiency.
