]]> The Marelon by Forespar 3-Way Y Valve is a reliable diverter valve designed for marine sanitation systems. It allows boat owners to control the flow of waste from a marine toilet, directing it either to a holding tank or to an overboard discharge line where regulations permit.

Manufactured from Marelon, Forespar’s advanced glass-reinforced polymer, this valve provides excellent resistance to corrosion, electrolysis, and harsh marine environments. Unlike metal fittings, Marelon components will not corrode or seize, making them particularly suitable for long-term installation in sanitation systems.

The valve operates through a simple manual lever that clearly indicates the selected flow direction, allowing quick and secure switching between discharge routes. It is commonly used in combination with marine toilets such as Jabsco manual and electric toilet systems, where a Y valve is required to comply with different waste management setups.

Available in two sizes to suit standard marine sanitation hose diameters, the Marelon Y valve is widely used in both sailboats and motorboats due to its durability, smooth operation, and dependable sealing performance.
