Height Control Valve – Dynamic Leveling Core for Commercial Vehicle Air Suspension
Height control valve dynamically adjusts airbag height. PTFE seals and linkage mechanism for heavy-duty applications; requires professional calibration.
Description
The Height Control Valve (Part No. 4640060020) is the intelligent leveling core of commercial vehicle air suspension systems, dynamically adjusting airbag pressure (response ≤0.3s) via linkage mechanism to maintain body level (height deviation ≤±2mm). Featuring hard-anodized aluminum valves and PTFE seals (-40℃~150℃), it operates at 0.4~1.2MPa, compliant with ISO 4414 and SAE J2194. Key functions:
- Dynamic Load Compensation: Auto-adjusts airbag height per axle load distribution.
- Real-Time Leveling: Prevents cargo tilting risks during motion.
- Inter-Axle Sync: Multi-valve coordination with ≤0.05MPa pressure differential.
Key Importance:
- Driving Safety: Height failure risks bridge strikes or rollovers.
- Material Impact:
- Anti-Corrosion: 304 stainless stem with ≥25μm hard chrome plating.
- Low Friction: PTFE+graphite seals reduce resistance (≤5N).
- Lightweight: Aluminum body reduces weight by 35%.
Replacement Guidelines:
- Linkage Calibration: Set reference height with tools like WABCO HCS (≤0.5mm error).
- Lubrication: Use silicone grease (e.g., Molykote 111) exclusively.
- Multi-Valve Logic: Configure master-slave priority via CANoe to avoid conflicts.
