PRODUCT DESCRIPTION
Genuine Factory Build & Precise Fluid Control
This AVU valve (OE:3541310-E9300) adheres to Dongfeng’s genuine part standards, built with aluminum alloy housing (corrosion-resistant) and a precision-machined valve core. It undergoes 10-bar pressure testing (ISO 9001-certified) to ensure zero leakage—critical for regulating engine fluid pressure. Unlike aftermarket valves, it matches the original flow rate (±2% tolerance), avoiding engine performance fluctuations.
Perfect Compatibility & Leak-Free Operation
It is fully compatible with Dongfeng models equipped with LoongGine Engine. To confirm fitment, cross-check your engine model or existing valve OE number with 3541310-E9300. The valve’s factory-machined mounting holes align exactly with engine brackets—eliminating custom adjustments (a common issue with generic valves) and preventing fluid leaks that cause engine damage.
Enhance Engine Efficiency & Durability
As a key engine fluid component, this valve maintains stable pressure control, reducing fluid system wear by 40% (per Dongfeng fleet data) during long-haul trips. Its aluminum housing withstands 120℃ operating temperatures, ensuring performance in extreme conditions. It also extends the service life of connected fluid components (pipes, pumps) by 30% via consistent pressure regulation.
