Solenoids

When every second counts on the road or jobsite, your equipment’s performance hinges on the smallest components – like the solenoid, the behind-the-scenes workhorse that keeps everything in motion.

 

A solenoid is a simple but powerful device – an electromagnetic coil that converts electrical energy into mechanical motion. In the world of heavy machinery and trucking, solenoids are essential for starting engines, controlling valves, and managing countless automated processes. 

 

Over the years, solenoid technology has evolved from basic magnetic switches to high-performance units designed for demanding industrial applications. Today’s solenoids are built for durability, precision, and efficiency – qualities every fleet operator can depend on. 

 

At Fitzgerald Truck Parts, we know how crucial solenoids are for keeping your operations running smoothly. Our selection is built to meet the performance and reliability demands of today’s equipment.

Types of Solenoids and Their Applications

Solenoids aren't one-size-fits-all. We carry a range of components tailored for specific uses. Whether you're looking for a starter solenoid to get your engine roaring or a solenoid valve to manage fluid flow, we've got you covered. Our inventory includes:

  • Valve solenoids: Best for controlling air, fuel, and hydraulic flow in trucks and equipment.
  • Starter solenoids: Reliable solutions for ignition and engine control.
  • Solenoid air valve: Designed to handle pressurized air systems in trailers and pneumatic controls.

We also supply both AC and DC models, depending on your system's electrical needs. AC solenoids tend to be more powerful for fixed machinery, while DC options offer smoother, more reliable function for mobile applications like trucks.

Selecting the Right Solenoid: Features and Specifications

When it's time to buy solenoids, getting the right specs makes all the difference. Key features to consider include:

  • Voltage and current ratings: Match these to your vehicle's system to avoid burnout or power loss.
  • Duty cycle: Determines how long the solenoid can stay energized before needing rest.
  • Stroke and force: Important for controlling mechanical movement with precision.
  • Mounting and connector types: Compatibility is key for secure installation.

These details impact performance and longevity. That's why we offer downloadable spec sheets and clear wiring diagrams -- so you can install with confidence and avoid mismatches. The right solenoid valves will always reflect your equipment's unique requirements, and we're here to help you find them.

Solenoid Pricing and Value: A Comprehensive Guide

We understand that pricing matters. But it's not just about finding the cheapest part -- it's about getting a component that lasts. We price our solenoids based on build quality, leading brands we trust, and real-world performance.

Choosing our solenoids means fewer replacements, minimized downtime, and reduced service calls -- giving you better long-term ROI. While browsing, look out for special offers that bring even greater value to your cart.

We encourage comparing suppliers, but remember: our parts come with full support, quick fulfillment, and reliability you won't find with discount alternatives.

Solenoid Installation and Maintenance

Installing a solenoid doesn't have to be complex. Follow these basic steps for optimal results:

  • Confirm all wiring matches your system's requirements.
  • Check mounting surfaces for stability and corrosion.
  • Connect securely and test activation under load.

For maintenance, inspect wiring regularly, clean any debris, and listen for odd sounds during activation. Most failures are avoidable with basic upkeep. If you're experiencing weak actuation or failure to engage, inspect your system's temperature performance -- excessive heat or cold can degrade response time.
