The Kleinn Model 6880 BlastMaster Valve Upgrade Kit is specifically engineered for the Model 630 Titan triple train horn system to dramatically increase air flow and push your horns to their absolute maximum decibel potential. This high-performance kit provides two additional VX6003 electronic solenoid valves, an oversized 1/2" impact-resistant air line, and all the necessary premium brass fittings required to route a dedicated, separate solenoid to each individual train horn trumpet. By eliminating the need for the individual air horns to share air from a single source, this upgrade delivers an unrestricted, massive volume of air directly to each trumpet, boosting the sonic output to a mind-blowing level. Please note that this kit is specifically designed as an upgrade for Model 630 horns currently utilizing the Model 307 solenoid valve.
