GROCO 1/2" NPT 90° Bronze Fuel Valve

The GROCO 1/2" NPT 90° Bronze Fuel Valve (model FV-590) is a compact fuel isolation valve engineered for marine and fuel system applications requiring reliable on-demand flow control. The bronze construction provides corrosion resistance in saltwater and freshwater environments, making it ideal for boat fuel systems, RVs, and other remote fuel tank installations where flow direction and material compatibility are critical.

The 90° flow path design enables space-efficient installation in confined engine compartments and tight plumbing layouts. The valve features 1/2" NPT male and female ports, allowing flexible integration into standard fuel line configurations. The compact form factor and bronze material weight of just 0.55 lbs minimize installation load while maintaining structural integrity under normal fuel system pressures. Users should note that the FV-590 brass variant suits fiberglass tanks, while the FV-590-S stainless steel option is specified for aluminum or stainless steel tank applications to prevent galvanic corrosion.

This fuel valve addresses the need for manual fuel isolation in marine vessels, auxiliary fuel systems, and equipment where shutoff capability prevents spillage during maintenance, storage, or emergency conditions. Tank material compatibility is essential—selecting the correct variant (brass for fiberglass, stainless steel for dissimilar metals) ensures longevity and prevents corrosion failure. The GROCO FV-590 is recognized in the marine industry for dependable valve performance in both fresh and salt water service.
