GROCO 1/2" 5-Port Tank Selector Valve

The GROCO 1/2" 5-Port Tank Selector Valve is a marine-grade manifold designed for vessels and mobile systems requiring multi-source fluid management. This selector valve enables operators to direct fuel or water from a common inlet to any of four separate tank or system outlets, making it essential for larger vessels, RVs, and auxiliary equipment where redundancy and selective sourcing matter. Built to withstand harsh saltwater and freshwater environments, this component is trusted by marine technicians and system integrators managing complex fluid distribution networks.

The FV-550-L utilizes a mechanical rotary selector design with a bottom-mounted common port, allowing unrestricted full 1/2" flow across all pathways. Each handle position delivers an audible click feedback, confirming positive engagement and reducing the risk of accidental mid-position operation. The thru-panel mounting configuration permits installation directly into bulkheads or compartment walls, while the compact 5 x 5 x 5 inch footprint minimizes space consumption in tight installations. Constructed from corrosion-resistant materials, the valve resists galvanic degradation common in marine environments, ensuring long-term durability and consistent operation.

Professionals managing fuel systems on fishing vessels, cruising sailboats, and work boats rely on this selector valve to alternate between primary and auxiliary tanks without shutting down engines or systems. RV and mobile equipment operators use it for managing separate freshwater and greywater supplies simultaneously. Installation requires 1/2" NPT or compression-compatible plumbing connections; ensure all ports are properly sealed or blocked if unused. At 1.95 lbs and rated for both fuel and potable water applications, this GROCO valve delivers marine-certified reliability for mission-critical fluid routing.
