Forespar® 'Y'-Valves and Connectors are molded from Marelon®. Offering an improved, stronger handle design, our valves are available in 1" (24.50mm) and 1-1/2" (38.00mm) barb size. 'Y'-Valves are an essential piece of equipment when the flow of water or other fluids are required to be conveniently diverted, as in a marine head application where a holding tank is utilized. They are easily mounted to a bulkhead. The valves are operated by a simple 120° movement. Positive stops are provided between positions. Replacement parts are available.
