Widely used in automotive brake systems, fuel systems, engine systems and air conditioning systems.

• Brake valves control vehicle braking pressure to achieve deceleration and parking
• ABS valves are core components of the anti-lock braking system, preventing wheel lock during braking and improving braking safety
• Fuel valves control fuel delivery and cut-off to ensure normal engine fuel supply
• Air conditioning valves regulate the cooling and heating flow of automotive air conditioners

• Material Selection: Must meet standards with aluminum alloy or forged steel preferred for brake and ABS valves
• High Precision: Coaxiality controlled within ±0.003 mm, aperture tolerance ≤ ±0.005 mm
• Surface Treatment: Anti-rust processes including anodizing, galvanizing and electrophoretic coating with anodizing layer thickness ≥ 10 μm
• Precise Matching: No clearance or jamming between valve core and valve body with precision grinding required
• Post-Processing Tests: Vibration, high-temperature, sealing and durability tests to ensure stable operation under extreme conditions

• Must have automotive-grade certification (ISO/TS 16949) and comply with OEM technical standards
• Must meet high-temperature and anti-vibration requirements with response time ≤ 5 ms
• Prioritize OEM or first-tier quality valve bodies with strict factory inspection
• Inspect surface treatment: no scratches, oxidation or rust; clear interface threads; smooth valve core movement

• Maximum processing outer diameter: 60
• Minimum control tolerance: 0.001
• Equipment: Japanese CNC Tsugami, CNC Citizen, multi-station cold extrusion forming machines, 500T press machines, casting equipment
• Workforce: 300 employees including 20 technicians, 10 engineers, and 15 quality control personnel
• Certifications: 8S management, ISO9001 and TS16949 automotive certifications
