Overview

The Kleinn Model VX6003-HK is an upgrade kit for onboard air systems, designed to maximize airflow and eliminate restrictions. It features the Vortex 6 valve, a heavy-duty brass solenoid with an enlarged internal orifice for faster air movement, providing instant response for train horns and air suspension. The kit can manage pressures up to 300 PSI and can function as an ultra-high-flow solenoid or an automatic air tank drainage system to purge moisture and prevent rust.

Part #: VX6003-HK

The VX6003HK features a 1/2" NPT air inlet and 12 mm orifice for increased airflow and sound levels. The more air that gets in to your horn the higher the decibel output will be. These upgraded Vortex valves have a higher air flow than the standard Kleinn valve and will make the horns louder. This kit can also make Kleinn horns compatible with higher pressure air systems. The kit includes the upgraded valve, 12 ft of 1/2" tube, and the necessary fittings and adapters.
