Commercial Vehicle Pneumatic & EBS/TEBS Brake System Components

Description

Key Features:

• ​Compliance: Meets ISO 7638, SAE J1939, and ECE R13 standards.
• ​Material Durability: Stainless steel valves, FKM/EPDM seals, and shielded cables for harsh environments.
• ​Redundant Safety: Dual-release valves and multi-channel relay systems prevent single-point failures.

This list includes core components for commercial vehicle pneumatic and electronic brake systems (EBS/TEBS), designed for ​air suspension and redundant braking, compliant with ​ISO 7638, ​SAE J1939, and ​ECE R13:

1. ​EBS Solenoid Valve (4801020640): ECU-driven stainless steel valve with ≤0.05s response time for precise pressure control.
2. ​Dual Release Valve (9630010510): Redundant pressure release, leakage ≤0.03mL/min @1.5MPa.
3. ​Four-Port Relay Valve (9710020400): Multi-channel pressure distribution for ABS/EBS 4S/2M logic.
4. ​Pneumatic Interfaces:
   • ​Yellow Connector (9522010010): IP69K-rated air suspension port with EPDM seals.
   • ​Red Connector (9522010020): Emergency brake port with FKM seals (200℃ resistant).
5. ​Cables & Labels:
   • ​3m Sensor Cable (4497230300): Twisted-pair shielded cable (≤0.2dB/m loss).
   • ​TEBS/EBS Labels: Oil-resistant PVC labels compliant with ISO 3779 traceability.

Key Importance:

• ​Redundancy: Dual valves eliminate single-point failure risks.
• ​Material Impact:
  • ​Valve Durability: 316L stainless steel and PTFE seals resist corrosion.
  • ​EMI Protection: Double-layer shielding (≥85% coverage) blocks interference.

Replacement Guidelines:

1. ​Sealing: Clean interfaces with isopropyl alcohol; silicone-free lubricants only.
2. ​Calibration: Use WABCO tools to program ECU parameters with VIN.
3. ​Label Compliance: Ensure label content matches EBS parameters for annual inspections.
