Description

This 4 in. Scupper Valve is made from Carbon Steel, Cast with a Flanged connection with a Class 150 pressure rating.

Scupper Valves are specialized one-way marine check valves designed for sewage and waste water drainage. They feature an offset inlet and outlet which allows flow while a check mechanism prevents backflow. Scuppers typically have a closure device called a gag, which allows the valve to be manually closed while in port. Scuppers are also called storm valves.

Flanged connections utilize flat circular plates with bolt holes to join piping components. The flanges are bolted together with a gasket in between to create a secure, pressure-tight seal. Flanged connections are valued for their ability to be assembled and disassembled without cutting pipe, making them essential for maintenance and system modifications.

Carbon Steel is the most common and widely used form of steel worldwide due to its strength, workability, and cost. Carbon Steel is an alloy of Iron that uses carbon as the primary alloying element. As a term, Carbon Steel generally means the component does NOT qualify as Stainless Steel, which is more resistant to corrosion.
