Production of high-pressure common rail safety valve 095420-0161 Denso safety valve

The high-pressure common rail safety valve 095420-0161 (Denso safety valve) is a key component in the diesel engine electronic injection system. It is mainly used to adjust the pressure in the high-pressure oil rail to ensure the stability of system operation.

The following is a specific introduction:

1. Core parameters

Model

Applicable system

Structural parameters

Electrical performance

2. Functional characteristics

Pressure adjustment

When the oil pressure exceeds the set threshold, the valve spool displacement is controlled through a solenoid valve to release excess pressure to the low pressure oil passage to prevent high pressure damage to the injector and other components

Adopt spring-type or electromagnetic control structure (subject to product design), which has fast response speed and high reliability.

System protection

Prevent abnormal fuel injection caused by pressure fluctuations and ensure stable combustion efficiency and engine power output.

3. Application and adaptation

Application scenario: High-pressure common rail systems for diesel engines such as Cummins are common in construction machinery and heavy vehicles.

 

FAQ

How many production lines in your factory?

5 production lines

 

What is your MOQ?

100 pieces

 

Can you design the equipment according to our size?

Yes

 

What is the function of a high-pressure common rail safety valve?

The safety valve protects the fuel system by relieving excessive pressure in the common rail, preventing damage to components and ensuring safe engine operation.

 

What causes a common rail safety valve to open?

It opens automatically when fuel pressure exceeds the design threshold (typically around 1,600–2,000 bar), allowing fuel to bypass and reduce system pressure.

 

What are signs of a faulty safety valve?

Symptoms include loss of fuel pressure, hard starting, engine stalling, poor performance, or diagnostic trouble codes (DTCs) related to pressure control.

 

How is the safety valve tested during production?

Each valve undergoes high-pressure sealing, response, and leak tests to ensure it opens and closes within precise tolerances and maintains fuel rail integrity.

 

Can a faulty safety valve be repaired, or must it be replaced?

Due to the precision and safety-critical nature of the valve, it is generally recommended to replace it rather than attempt repair.
