Del Check Valve Kit
Bendix

This delivery side check valve kit provides unidirectional airflow within the air system, protecting the compressor and pressure vessels from reverse flow during rapid pressure changes and shutdown cycles. By maintaining a stable pressure differential, it minimizes compressor cycling stress and reduces contaminants migrating toward sensitive control components. The kit's components are designed for compatibility with standard Bendix air system configurations, supporting straightforward diagnostics and field replacements. Operators benefit from improved brake response consistency, reduced risk of pressure bleed during unload cycles, and enhanced system integrity in high-vibration environments. The part aligns with the VMRS 013-010-176 category lineage and integrates with common reservoir and control valve assemblies, making it a practical upgrade or replacement option in fleets prioritizing predictable braking performance and reduced downtime. Cross-functional compatibility with related valve bodies and upstream piping ensures reliable assembly fits in a variety of heavy truck applications, including long-haul and vocational duty cycles.
