GROCO 1-1/2" NPT Bronze In-Line Ball Valve

The GROCO 1-1/2" NPT Bronze In-Line Ball Valve is engineered for marine, industrial, and plumbing applications where reliable fluid control is essential. This full-port ball valve delivers dependable on-off service in saltwater, freshwater, and general utility systems. Designed for professionals and OEM integrators, it combines corrosion-resistant bronze construction with practical maintenance features that extend service life in demanding environments.

The valve features female NPT threads for secure connection to standard pipe fittings, enabling fast installation in any orientation. The 1-1/2" bore provides unrestricted flow when fully open, minimizing pressure drop across the line. A selectable handle rotation allows you to position the lever for optimal ergonomics in tight spaces or to match existing system layouts. Larger sizes (1-1/4" and above) include a grease zerk fitting for in-service lubrication—apply grease only when the valve is open—or for system draining without disassembly.

This valve is ideal for deck washdown systems, bilge applications, water transfer, fuel distribution, and agricultural irrigation where corrosion resistance and durability matter. Bronze resists galvanic attack in saltwater and brackish environments, making it a preferred choice for coastal and offshore installations. The compact 6 x 3 x 8 inch footprint fits easily into confined engine rooms and equipment bays. Whether you're specifying replacement components for a vessel, upgrading a marine system, or building a new industrial circuit, this GROCO ball valve delivers proven reliability with minimal maintenance overhead.
