GROCO 3/4" NPT Bronze 3-Way Valve

The GROCO 3/4" NPT Bronze 3-Way Valve (model TWV-750) is a diverter valve engineered for fluid transfer applications in marine, RV, and industrial systems where directional flow control is essential. This bronze 3-way valve uses a logical 180° rotating handle that points toward the direction of flow, eliminating guesswork during operation. The center position locks the valve in the "off" state, providing positive isolation when needed. Built with stainless steel handle and hardware, PTFE seals and seats, and a mounting foot included, this valve delivers full flow capacity and is UL-listed for both fuel and water applications.

The 3/4" NPT threaded connection is the industry standard for mid-sized fluid systems, offering compatibility with most hose and pipe configurations without adapter requirements. Bronze construction provides corrosion resistance superior to ferrous alternatives, making it ideal for saltwater environments and applications exposed to moisture and oxidation. PTFE (polytetrafluoroethylene) seals ensure reliable performance across temperature variations and fluid types, critical in systems handling both fresh and saltwater or mixed fuel grades. The full flow design minimizes pressure drop, preserving system efficiency in applications where throughput demands are high.

This valve serves boat systems requiring selectable tank switching, RV water supply distribution, fuel management in dual-tank vehicles, and industrial fluid diversion in processing plants. The intuitive handle-points-to-flow design reduces operational errors—critical in emergency situations or when multiple crew members operate the system. The integrated mounting foot simplifies installation on bulkheads, dashboards, or equipment frames without secondary brackets. UL certification for both fuel and water affirms its suitability across recreational and commercial applications where regulatory compliance is required.
