GROCO 2" Bronze In-Line Check Valve

The GROCO 2" Bronze In-Line Check Valve (model CV-200) is a one-way flow control device engineered for fluid systems requiring reliable backflow prevention in marine, industrial, and fuel handling applications. Constructed from C83600 cast bronze, this 2-inch check valve delivers corrosion resistance and durability in salt-air environments while maintaining consistent performance across both diesel fuel and gasoline systems.

The in-line design with NPT (National Pipe Thread) threaded ports allows straightforward installation into existing 2-inch fluid lines without requiring additional adapters or fittings. Cast bronze construction offers superior longevity compared to lighter alloys, particularly in applications exposed to thermal cycling or corrosive fuel additives. The check valve operates passively—allowing forward flow while automatically closing under reverse pressure—eliminating the need for electric controls or maintenance procedures. This passive operation makes it ideal for gravity-fed systems, engine cooling loops, and fuel transfer applications where reliability cannot depend on external power sources.

This valve is specified for fleet operators, marine vessel plumbing systems, agricultural fuel infrastructure, and industrial fuel distribution where a 2-inch check valve in bronze is the standard component. The model's compatibility with both diesel and gasoline makes it versatile across multiple fuel types and fleet compositions. GROCO check valves are OEM-equivalent components trusted in commercial maritime and industrial settings where downtime from valve failure creates operational and safety risks.

The 2-inch NPT threaded port size and bronze material composition are industry standards for medium-flow fuel and fluid systems, ensuring the valve integrates with existing marine-grade plumbing and industrial fuel handling infrastructure.
