Description
Product Overview
Part Name: Electronic EGR Proportional Control Valve
Part Numbers: 202V25902-0103 / 202V25902-0110
Vehicle Compatibility: Fits Sinotruk HOWO, HOWO A7, HOWO T5G, HOWO T7H, Sitrak C7H/C5H and CNHTC National IV–VI diesel trucks equipped with electronically managed EGR emission systems (2012–2024).
Configuration: High-precision proportional EGR valve featuring electrically modulated flow control, reinforced stainless-steel valve core and OE-calibrated electronic connectors for stable exhaust recirculation.
Function: Actively regulates the amount of exhaust gas routed back into the intake, lowers NOx emissions, stabilizes combustion temperature, and maintains optimal performance under varying load conditions.
Technical Specifications
Type: Electronic proportional EGR valve engineered for electronically controlled National IV–VI Sinotruk engines (MC11/MC13/WD615) requiring dynamic exhaust-flow modulation.
Material: Hardened steel valve body with heat-resistant actuator coil, carbon-resistant sealing rings and corrosion-proof electrical terminals.
Application: Direct-fit replacement for HOWO, HOWO A7, T5G, T7H and Sitrak trucks using 202V25902-series valves with OEM-matched flow curves and mounting geometry.
Cross-Reference: Matches CNHTC factory specifications for EGR actuator response rate, exhaust-flow accuracy, thermal resistance and long-term durability.
Installation: Replace when experiencing EGR-related fault codes, fluctuating idle, reduced power, excessive exhaust smoke or unstable boost pressure.
Service Interval: Recommended every 200,000–350,000 km depending on duty cycles, fuel quality and engine soot levels.
