Discriminator Valve 1.5in Diameter

The Discriminator Valve 1.5in Diameter from ATL FUEL CELLS is a crucial component for safety and flow control in high-performance fuel cell systems and motorsport applications. It is designed for use in competition vehicles, vintage race car restorations, and modern performance engine upgrades that require auxiliary fuel storage.

This precision-engineered valve prevents fuel backflow and maintains system integrity under extreme conditions. It features a spring-loaded check mechanism that opens under positive fuel pressure from the primary source while sealing immediately if secondary tank pressure exceeds primary pressure, effectively preventing siphoning and cross-contamination.

Engine builders, fabricators, and motorsport teams will find this valve indispensable for setups involving multiple fuel sources. Its compact footprint and lightweight construction make it suitable for extended track duty or long-distance driving with redundant fuel capacity.
