DESCRIPTION
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.
