Description
### Product Overview
The injector control valve assembly is installed inside the common rail injector. It achieves the on-off of high-pressure fuel through the cooperation of springs and valve cores, precisely controlling the opening and closing times of the fuel injection. Under the long-term erosion by impure fuel and the high-frequency reciprocating impact conditions, the sealing surface of the valve core will wear, the spring elasticity will decline, and the base will be worn. This will cause fuel pressure leakage and abnormal injection. This product is standardized in terms of its size and spring force parameters. When the injector is disassembled for maintenance, the entire set can be replaced, effectively restoring the fuel injection accuracy. It is suitable for the maintenance of diesel construction machinery, heavy vehicles, and common rail engines.
Core advantages of individual products
1. **High-strength alloy steel valve core, resistant to wear and high pressure, not prone to wear**
The valve core is precisely machined from high-quality alloy steel and undergoes surface strengthening treatment. Under long-term high-frequency reciprocating operation, the sealing surface is not easily scratched, and it can withstand continuous high-pressure fuel impact and resist impurity particle erosion.
2. **Precise formed pressure spring, stable and persistent elastic force without attenuation**
The spring is made of high-quality spring steel and undergoes tempering and forming treatment. The elastic force parameters are uniform, and it is not prone to fatigue deformation under long-term load, ensuring stable response speed of fuel injection opening and closing.
3. **High-precision limit base, precise positioning, high assembly coaxiality**
The contour of the base and the size of the positioning columns are strictly controlled. After assembly, the valve core runs in a coaxial manner, reducing the probability of sticking and maintaining a stable sealing effect.
4. **Strict gap matching for complete factory delivery, reducing the difficulty of maintenance and debugging**
The internal parts of the kit are paired and verified in pairs, and the mating gap reaches the standard range. After maintenance and assembly, the fuel injection parameters can be quickly restored, significantly reducing the maintenance time.
5. **Resistant to alternating high and low temperature conditions, adaptable to complex working environments**
The entire component material performance is stable. Under alternating conditions of low-temperature cold start and continuous heavy-load high-temperature, the performance fluctuation is small, and there is little risk of fuel injection failure.
6. **Performance testing of each batch of kits is conducted in sequence, with high consistency of individual pieces**
Each batch of the kit undergoes sealingity and opening and closing response sampling tests. The parameters are uniform, and the stability of maintenance, spare parts supply, and assembly is stronger.
