Product overview
The WL10938 metering valve solenoid from Weilong Technology is a precision electromagnetic actuator for controlling fluid flow, dosing and valve positioning in industrial systems. It is available in DC 12 V and DC 38 V variants and offers configurable stroke, force and duty cycle for integration with automated equipment.

How it works
The coil generates a magnetic field when energized, moving a plunger that mechanically actuates the metering valve. Varying voltage, current or pulse signals permits accurate valve positioning to control flow rate, dosing volume or pressure. The unit is designed for repeatable linear movement and predictable response time.

Main features

• Precise flow control and repeatable dosing
• Fast response and stable actuation
• Compact carbon-steel housing with zinc plating
• Configurable: voltage (DC 12/38 V), stroke 3–10 mm, push/pull force 1–60 N
• Wide operating temperature: -10 °C to 100 °C; duty cycle 1–100%
• Compatibility with PLCs and industrial automation

Applications

• Chemical process dosing and additive injection
• Industrial automation: dispensers, filling and production lines
• Hydraulic and coolant flow regulation
• Laboratory and medical liquid dosing (when specified)
• Agricultural equipment for fertilizer/pesticide distribution
• Automotive and specialty fluid control systems

Advantages

• High dosing accuracy and repeatability
• Low power consumption with optimized coil design
• Long operational life when used within specified ratings
• Reduced manual adjustments and straightforward automation integration

Limits and precautions

• Higher unit cost versus basic ON/OFF solenoids due to precision design
• Requires appropriate electrical control and correct duty-cycle selection to avoid overheating
• Sensitivity to fluid contamination — filtration and maintenance recommended
• High-force or long-stroke needs may require larger or different variants

Troubleshooting (common issues and checks)

• No operation: verify supply voltage, wiring, coil resistance and control signals
• Reduced travel: check operating voltage, load conditions and internal contamination; clean valve internals
• Overheating: confirm duty cycle vs rating, supply voltage and heat dissipation
• Dripping/leakage: inspect/replace seals and remove debris
• Unusual noise: check mounting torque, mechanical wear and foreign particles
