Denso Common Rail Injector Valve Plate

The Denso Valve Plate (also known as the Orifice Plate) is a vital control component located within the common rail injector assembly. It plays a crucial role in regulating fuel return flow and maintaining the precise hydraulic pressure required for optimal injection timing. Manufactured from high-grade, heat-treated steel, this valve plate is engineered to withstand the extreme operational pressures of modern diesel engines.

This specific valve plate is designed for compatibility with Denso G2 and G3 series injectors, widely used in vehicles such as Toyota (Hilux, Land Cruiser), Isuzu (N-Series, D-Max), Hino, and John Deere heavy machinery. Over time, the sealing surface of the original plate can wear down due to fuel impurities, leading to symptoms like hard starting, engine stalling, or excessive black smoke. Installing our replacement valve plate effectively resolves these issues by restoring the injector's sealing integrity. Each plate undergoes strict microscopic inspection to ensure the orifice diameter and surface flatness meet OEM specifications.

• Precision Engineering: The orifice hole is drilled with microscopic accuracy to ensure exact fuel flow rates and consistent injection timing.

• High Wear Resistance: Made from hardened bearing steel with a specialized surface treatment to resist erosion from high-pressure fuel.

• Leak Prevention: The ultra-flat sealing surface ensures a tight seal with the control rod, preventing fuel back-leakage and pressure loss.

• Cost-Effective Repair: Allows you to rebuild a faulty injector at a fraction of the cost of buying a complete new injector assembly.

• Broad Compatibility: Fits a wide range of Denso injectors used in both passenger cars and heavy-duty commercial trucks.
