MODEL 307: VORTEX™ 4 CHROME 12-VOLT SOLENOID AIR VALVE

PROFESSIONAL GRADE PERFORMANCE

Bring rapid-fire pneumatic activation straight to your signaling setup with the premium Model 307 Vortex™ 4 Air Solenoid Valve. Utilized extensively on our compact air horns and smaller locomotive kits, this standard 12-volt cylindrical electronic valve is meticulously engineered for quick acoustic response and reliable high-pressure airflow control. Featuring a maximum operational pressure ceiling of 165 PSI, this valve ensures your horn receives a full, instantaneous burst of air line power every single time you hit the cockpit command button.

VERSATILE PLUMBING & NON-POLARIZED WIRING

The Model 307 is optimized for clean, space-saving plumbing integration, accepting a 1/4" O.D. high-pressure line directly into its pre-installed 200 PSI rated brass compression fitting inlet, paired with a heavy-duty 1/4" Male NPT outlet port. Electrical installation is exceptionally user-friendly; the two-wire electrical layout is completely non-polarized. Because the leads are non-polar, they can be utilized interchangeably for either your positive 12V horn signal output or chassis ground path, eliminating wiring confusion during custom integration. For large-diameter systems requiring extreme high-flow volume, step up to our heavy-duty Model VX6003 brass super-duty solenoid manifold valve.

Why Choose the 307 Solenoid?

  • Maximum Pressure Ceiling: Rated up to 165 PSI to comfortably handle robust, high-pressure automotive and off-road onboard air systems.
  • Dual-Wire Configuration: Non-polarized power lead wires allow interchangeable positive and ground hookups for a highly simplified installation loop.
  • Premium Cylindrical Finish: Sleek, mirror-polished chrome-plated casing offers excellent defense against road salt, engine compartment grime, and structural oxidation.
  • Precision Leak-Free Seals: Integrated 1/4" O.D. compression inlet fitting matches tightly with a 1/4" Male NPT threaded manifold block to isolate pressure drops.

THE VERDICT: The definitive electronic valve upgrade for crisp, rapid-fire horn performance. The Vortex™ 4 packs robust sealing architecture and a beautiful chrome casing into an ultra-reliable, compact footprint that integrates effortlessly onto any vehicle platform.
