Solenoid
A Solenoid is the high-speed heart of modern automation, designed to convert electrical energy directly into linear mechanical force. While general valves manage large-scale flow, Solenoid Valves excel in precision, high-frequency switching, and millisecond-level response times. The performance of these components is entirely dictated by the electromagnetic efficiency of the coil—where even a minor winding defect can lead to slow response, overheating, or failure in critical moments.
DETZO provides state-of-the-art automated systems for solenoid coil manufacturing, focusing on ultra-high-speed winding and 100% electrical integrity testing. Our technology ensures that every solenoid delivers consistent pull-force and rapid actuation for mission-critical applications. For high-precision solenoid solutions, please Contact DETZO.
If a standard valve is like a water faucet, a Solenoid is like a high-speed camera shutter. It doesn't just open and close; it does so with incredible speed—often hundreds of times per minute.
The "Instant-On" Physics： Inside the solenoid, the coil creates a magnetic field that yanks a metal plunger into position instantly. This requires the wire to be wound with zero internal gaps. Any "loose" turns in the coil act like a spring, dampening the magnetic force and delaying the valve's reaction time.
Heat Management： Because solenoids often stay energized for long periods or switch rapidly, they generate significant heat. Precision winding maximizes the "Copper Fill Factor," ensuring the coil generates maximum magnetic force with minimum electrical resistance, keeping the component cool and extending its lifespan.
Solenoids are classified by their actuation method and the precision of their control:
01. Direct-Acting Solenoids
Style: Small, compact units where the solenoid plunger directly opens/closes the orifice.
Description: Best for low-flow, high-speed applications like laboratory instruments. They require ultra-fine wire winding for rapid pulse response.
02. Proportional Solenoids
Style: Sophisticated actuators that can position the plunger at any point, not just fully open or closed.
Description: Found in medical ventilators and automotive suspension. These require perfect layer winding to ensure a linear relationship between current and force.
03. Pneumatic Solenoid Valves
Style: Often multi-valve "Manifolds" used in factory automation to control air cylinders.
Description: Built for millions of cycles. Focuses on low-power consumption and high reliability during continuous 24/7 industrial operation.
04. Automotive Solenoids
Style: Rugged metal housings with high-temp O-ring seals, often calibrated for hydraulic fluid immersion.
Description: Critical for automatic transmissions (TCU) and VVT systems. They must endure extreme vibrations and operate in hot oil (up to 150°C).
05. Latching Solenoids
Style: Compact modules with internal permanent magnets, featuring dual-coil or center-tapped winding structures.
Description: Only requires a pulse of power to switch states, then stays there without power. Ideal for battery-operated smart locks and irrigation timers.
