& Notes

Plastic ball valve, 1-1/2". Typically used for the direct overboard discharge for the head on boats that have a Y valve between the head and the holding tank. Used with an appropriate hose barb so that holding tank is not filled up requiring the use of the macerator pump to empty.

May also be a good substitute for the original ball valve used for the gravity emptied black water tanks Catalina used on the 350's.

Molded Marelon offers superior strength and corrosion resistance. Marelon is lightweight, corrosion and electrolysis free, ideal for thru-hull valves. Marelon is a modern material formulation of polymer composite compounds that uses resins and additives to produce an extremely strong marine-grade product that will not deteriorate like traditional bronze marine plumbing parts.

National Pipe Straight Mechanical (NPSM) threads used in marine fluid systems that requires thread compound or common PTFE pipe sealing tape tape to seal. The female component incorporates a straight, non-tapered thread with an inverted 30° chamfer of the male connector on the seat of the female. This is a mechanical seal.

• Thread type: 1-1/2" National Pipe Straight Mechanical
• Body diameter: 3-1/2"
• Body length: 5"
• Radius w/Handle: 3-1/4" (from centerline of fitting to outermost point with handle in closed position. Required space surrounding the valve to rotate valve onto fixed threaded fitting)
• Length of handle: 7"
• Total height (including handle): 7-1/2" valve is open
• Width w/Handle: 5" (from centerline of fitting to outermost end of the handle when valve is closed.

NOTE: Handle can rotate in either direction to close valve (handle perpendicular to flow).

1) The handle is perpendicular to the valve body when the valve is closed, parallel to the valve when open. The handle may be rotated 90 degrees in either direction form parallel to close the valve.

2) Depending upon the application, the valve may be mounted in any orientation (i.e. either end up for example).
