Direct-operated solenoid valve WL0521

2-wayfor watercompact

Product Overview
The Weilong WL0521 car headlamp solenoid valve is a compact electromagnetic actuator designed for projector-type automotive headlamps. It enables fast, precise switching between high beam and low beam by controlling the shutter mechanism. Constructed with a copper coil, iron core components and a carbon steel housing with high-temperature materials, it is engineered for the automotive environment and easy integration with bi-xenon and LED projector systems.

Key Features

• Fast electromagnetic response for rapid high-beam/low-beam switching.
• Compact, lightweight design for straightforward integration into projector assemblies.
• Low power consumption to minimize vehicle electrical load.
• Customizable stroke length and mounting options for varied projector designs.
• Compatible with HID (Xenon), halogen and LED projector headlamps.

Operation and Reliability
The solenoid generates a magnetic field that moves the plunger to operate the shutter/cutoff plate; a return spring repositions the mechanism when de-energized. The WL0521 is designed to withstand temperature fluctuations, vibration and frequent switching cycles, providing consistent beam alignment and extended operational life for automotive lighting systems.
