Product Specifications

Technical details and manufacturing context for Solenoid Valve (Electronic)

Definition
This product is an electronically controlled solenoid valve, classified as a component for motor vehicle manufacturing. It is a part-level item designed for integration into fuel injection pump systems. The valve precisely controls the timing, duration, and quantity of fuel delivered to the engine's combustion chambers by opening and closing in response to electrical signals from the engine control unit (ECU). The working principle involves the ECU sending an electrical current to the solenoid coil, creating a magnetic field that moves a plunger or armature, opening the valve to allow fuel flow. When the current is cut off, a spring returns the plunger to its closed position, stopping fuel flow. This on/off action is precisely timed to control fuel injection. The valve is constructed from materials including electrical steel for the solenoid core, copper for the winding, stainless steel for the valve body, and elastomer seals for sealing. Key parameters include a flow rate of 15–60 L/min at Δp 0.1 MPa, a response time of ≤10 ms at rated voltage, coil resistance of 12–48 Ω at 20°C, supply voltage of 24 ±10% V DC (other voltages on request), power consumption of 8–15 W (holding power), operating temperature of -40–85°C (ambient and media), ingress protection of IP54–IP65 depending on connector (per IEC 60529), body material of 316L stainless steel (per ASTM A276), seal material of FKM (per ASTM D2000), weight of 0.3–0.8 kg without connector, and leakage rate of ≤0.1 mL/min at rated pressure (per ISO 5208). These values are directory reference ranges and must be confirmed for the actual model and application. The product is listed in a neutral directory; it is not manufactured or sold by the directory. Always verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
The engine control unit (ECU) sends an electrical current to the solenoid coil, generating a magnetic field that moves a plunger or armature. This movement opens the valve, allowing fuel to flow. When the current is interrupted, a spring returns the plunger to its closed position, stopping fuel flow. The precise timing of this on/off action controls the fuel injection process, ensuring accurate delivery of fuel to the engine.

Risk, maintenance & compliance

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Coil Burnout
Cause: Overvoltage, excessive heat due to prolonged energization, or poor electrical connections leading to insulation breakdown and short circuits.
Spool Sticking or Binding
Cause: Contamination from particulates, moisture, or debris in the fluid medium, causing mechanical obstruction and preventing proper movement of internal components.
Maintenance Indicators
  • Audible humming or buzzing without valve actuation, indicating coil energization failure or mechanical obstruction.
  • Visible fluid leakage around the valve body or solenoid housing, suggesting seal degradation or physical damage.
Engineering Tips
  • Install a properly sized filter upstream to protect the valve from particulates and ensure clean, dry compressed air or fluid supply.
  • Implement preventive maintenance schedules to inspect electrical connections, verify coil resistance, and test valve response times to detect early degradation.
