Vixen Horns 12V Electric Air Valve Solenoid VXA7164 — 1/4" NPT, Chrome-Plated, High-Flow 200 PSI

If you run an electric air horn or train horn on a vehicle, the VXA7164 solenoid provides a durable, high-flow way to control airflow from your tank to the horn. Built with a metal body and chrome plating, this normally-closed valve stays sealed until energized by a 12V signal, giving precise, repeatable horn actuation without the leaks or restrictions common to cheaper fittings.

How quickly will this valve activate my horn?

The VXA7164 is a fast-response 12V solenoid engineered to open immediately when energized, minimizing lag between pressing the switch and horn sound. Its improved high-flow inner core reduces turbulence and pressure drop so your horn receives strong, consistent airflow.

• 12V normally-closed design for instant opening under power
• High-flow interior lets maximum air pass to the horn
• Optimized for minimal activation lag and clear horn output

What pressure and hose sizes does this valve support?

This valve is rated for up to 200 PSI, making it suitable for most automotive and truck train horn systems. It screws into any 1/4" NPT female port and includes a compression fitting sized for a 1/4" outer diameter hose with approximately 1/8" inner diameter.

• Maximum operating pressure: 200 PSI
• Thread: 1/4" NPT male to fit standard horn ports
• Includes 1/8" NPT male compression fitting for 1/4" OD hose

Is this valve durable and weather resistant for outdoor use?

The valve body is metal and chrome-plated, which provides an extra layer of corrosion resistance and wear protection compared with plastic components. That finish helps the solenoid withstand road spray, salt, and general outdoor exposure while maintaining a tight seal under pressure.

• Chrome-plated metal housing for weather durability
• Robust internal construction intended for daily operation
• Designed to resist leaks at high air pressures

How easy is it to install and connect this solenoid?

Installation is straightforward: the valve screws into a 1/4" NPT female horn port and the included compression fitting secures the air hose without barbs. The solenoid uses a standard 12V electrical connection; clear instructions are provided to guide hose routing and wiring so you can complete the install without specialized tools.

• Screws into standard 1/4" NPT female thread ports
• Includes 1/8" NPT compression fitting for secure hose attachment
• Simple 12V wiring for easy integration into vehicle electrical systems

Who is this for? The Vixen Horns VXA7164 solenoid is aimed at vehicle owners, installers, and hobbyists who want a reliable, high-flow valve for train and air horns that can handle elevated pressures and outdoor conditions. It suits professional installers upgrading a horn system as well as DIYers replacing an unreliable valve; if you need fast actuation, solid sealing at 200 PSI, and a weather-hardened metal body, this valve is a practical, long-lasting choice.
