Rotary Slide Valve – Multi-Channel Flow Control Core for Air Suspension

Description

The Rotary Slide Valve (Part No. ​4630320200) is a multi-channel airflow control core for commercial vehicle air suspension systems, enabling ​precise switching of pneumatic paths for airbag inflation, exhaust, and pressure balancing. Featuring a ​hard-anodized aluminum body and ​PTFE wear-resistant seals (-40℃~150℃), it operates at ​0.4~1.5MPa with ≤0.2s switching time and ≤0.03mL/min leakage (@1.0MPa), compliant with ​ISO 4414 and ​SAE J2194. Key functions:

1. ​Multi-Channel Control: 3/4-way design for air springs, tanks, and height valves.
2. ​Low-Friction Actuation: Laser-textured spool (Ra≤0.2μm) with grease grooves (friction ≤3N).
3. ​Redundant Protection: Mechanical stops prevent over-rotation and cross-pressure.

Key Importance:

• ​System Efficiency: Delayed switching risks leveling failure and cargo damage.
• ​Material Impact:
  • ​Lightweight: Aluminum reduces weight by 40% vs. cast iron.
  • ​Seal Durability: PTFE+bronze seals endure ≥5M cycles.
  • ​Corrosion Resistance: 20μm anodized layer passes 720h salt spray test.

Replacement Guidelines:

1. ​Orientation: Align valve arrow with airflow direction.
2. ​Lubrication: Replenish silicone grease (e.g., Krytox GPL 205) every 6 months.
3. ​Limit Calibration: Post-installation manual rotation test (0°~90°).
