Commercial Vehicle Air Suspension Core Components (Pressure Relief/Height Valves/Filters)

Description

Key Features:

• ​Compliance: Meets ISO 4414 and SAE J2194 standards.
• ​Material Durability: Aluminum alloy valves, PTFE/EPDM seals, and corrosion-resistant filters.
• ​Precision Control: Height valves with ±5mm limiter accuracy and rapid pressure regulation.

This list includes core components for commercial vehicle air suspension systems, compliant with ​ISO 4414 and ​SAE J2194 standards, covering pressure control, height adjustment, and air purification:

1. ​Pressure Relief Valve (4341001250): Regulates system pressure (0.6~1.2MPa) with aluminum alloy body and stainless spring (leakage ≤0.05mL/min).
2. ​Air Filter (4325000200): 5μm filtration efficiency, multi-layer fiber core for dust/water/oil removal.
3. ​Height Control Valves (4640060020/4640061000):
   • ​Standard: Dynamic height adjustment (≤0.3s response).
   • ​With Limiter: Mechanical limiter (±5mm accuracy) prevents over-inflation.
4. ​Air Line Connector (4334010030): Quick-connect nylon fitting (IP67, 1.5MPa pressure).
5. ​Rotary Slide Valve (4630320200): Multi-channel airflow control with PTFE seals (-40℃~120℃).

Key Importance:

• ​System Stability: Pressure relief and height valves prevent rollover or excessive vibration.
• ​Material Impact:
  • ​Lightweight & Corrosion Resistance: Aluminum reduces weight by 40% (720h salt spray tested).
  • ​Sealing Integrity: PTFE/EPDM ensures zero leakage.

Replacement Guidelines:

1. ​Pressure Calibration: Reset system pressure post-replacement (refer to OEM manual).
2. ​Filter Maintenance: Replace filter every 30,000 km or 12 months (harsh environments: 10,000 km).
3. ​Limiter Calibration: Use tools like WABCO VCS for limiter adjustment.
