Forespar Marelon Y-Valve 1½”

The Forespar Marelon® Y-Valve is a premium diverter valve designed for reliable flow control in marine plumbing and sanitation systems. Manufactured from high-strength, fiberglass-reinforced Marelon®, it offers exceptional durability, lightweight construction, and complete resistance to corrosion, making it an ideal alternative to traditional bronze valves.

Commonly used in marine head installations, the Y-Valve allows the flow of waste or water to be conveniently diverted between a holding tank and an alternative discharge line where regulations permit. The valve operates with a smooth 120° handle rotation, featuring positive stop positions for precise and secure operation.

Its service-friendly design allows the central diverter to be replaced without disconnecting the hoses, reducing maintenance time and simplifying repairs. Because Marelon® is both electrically and chemically inert, the valve is completely immune to electrolysis and requires no electrical bonding. It also offers outstanding UV resistance and maintains its strength without becoming brittle over time.

Manufactured to exceed ISO standards, approved by ABYC, and tested to the same demanding Marine UL standards as bronze valves, the Marelon® Y-Valve delivers dependable, long-term performance in demanding marine environments.
