Product Description
control valve
The control valve is a key actuator in industrial automation systems, and its core function can be summarized as follows:
1. Flow and pressure regulation
By changing the position or opening degree of the valve core, the flow rate and pressure of the fluid in the pipeline are dynamically adjusted to meet the process requirements. For example, in a boiler system, the control valve maintains the stability of the drum liquid level by adjusting the feed water volume.
Special types such as pressure reducing valves can lower the medium pressure, while distribution valves can distribute or mix the medium.
2. Temperature control
The temperature control valve (thermostatic valve) stabilizes the outlet temperature of the equipment by regulating the flow of cold and hot media. For example, in an air conditioning system, it automatically adjusts the valve opening according to the load changes.
3. Safety protection
The safety valve automatically releases the medium (such as in a steam system) when overpressure occurs, while the minimum flow circulation valve can prevent the pump from being damaged due to cavitation.
Fail-safe design (such as air-to-open/air-to-close valves) ensures that the system is in a safe state in case of emergencies.
4. Remote and automated operation
Electric control valves achieve remote opening and closing through electrical signals and are suitable for water supply and drainage or industrial automation systems.
When used in conjunction with accessories such as positioners and solenoid valves, it can enhance the response speed and control accuracy.

What is the function of the 9308-622B control valve?
The 9308-622B control valve regulates the precise timing and amount of fuel delivered by a common rail injector, ensuring accurate injection events and optimal engine performance.
Which injectors or engines is this valve compatible with?
It is commonly used in Delphi diesel injectors found in various passenger cars and commercial vehicles. Compatibility should always be confirmed with the injector model or OEM specifications.
What are symptoms of a faulty 9308-622B control valve?
Common signs include hard starting, misfiring, increased fuel consumption, excessive smoke, or injector-related diagnostic trouble codes (DTCs).
Can this control valve be replaced independently of the injector?
Yes. If the valve is the source of failure and the injector body is still in good condition, the 9308-622B can be replaced individually, which is a cost-effective solution.
Does it require calibration after installation?
In many cases, yes. Some injector systems require re-coding or re-calibration through diagnostic tools to ensure proper operation after control valve replacement.
