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.

  • Kleinn Compact Air Horns: Functions as a direct factory replacement electronic valve for all compact model configurations: 101, 102, 102-1, 130, 130-1, 141, and 141-1.

This warranty encompasses a promise that the product you have purchased will perform as expected under normal use conditions and will not suffer from flaws in materials or craftsmanship. However, it is important to note that this warranty does not cover any damage that results from abusive use, operation that is not in line with the product’s intended purpose, or harm resulting from exposure to harsh environmental conditions. In the event that a product is found to be defective within the warranty period following a thorough inspection, Kleinn Automotive Accessories reserves the right to either repair or replace the defective item at no additional charge to the purchaser. It is our goal to ensure that our products meet the high standards that our customers expect, but we also want to clarify that Kleinn is not responsible for covering any costs related to the installation of our products, nor are we liable for any loss or damage that may occur as a result of the repair or replacement process of any product under warranty.

Detailed Warranty Return Procedure:

Should you need to initiate a return under the warranty, we have a straightforward process designed to make it as convenient as possible for our valued customers. To start, you will need to email a copy of your sales receipt, which must be dated within the past year for standard warranty claims or within the past two years for claims under the extended warranty for the 6450 Compressors and 730 Horns.

Upon receipt of your email, a dedicated representative from Kleinn Automotive Accessories will reach out to you directly. Our first step will always be to attempt to resolve the issue through technical support, aiming to provide a quick and effective solution. If the problem cannot be addressed remotely, our representative will issue a Return Authorization number. This number is crucial as it will identify your return throughout the inspection process. You are then required to send the product back to Kleinn Automotive Accessories for a comprehensive physical inspection.

Upon inspection, if the product is determined to be defective due to issues in workmanship or materials, Kleinn will undertake to either repair or replace the product at our discretion. We are committed to ensuring that our customers receive products that meet our high-quality standards, and we will make every effort to resolve warranty claims to your satisfaction. However, if the inspection reveals that the product does not have a material defect, we will return the unit to the customer. In such cases, the shipping costs for the return will be the responsibility of the customer.
