Description

This 3 in. Swing Check Valve is made from 304SS, 316SS with a Flanged connection with a Class 600 pressure rating.

Swing check valves allow fluid to flow in only one direction, using a flapper or swinging disc that opens to enable forward flow and closes against reverse flow. These backflow preventers are critical in marine applications.

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.

Stainless Steel (SS) is a category of iron-based chromium alloys. Stainless Steel is notable for its resistance to corrosion from chemicals, seawater, and other fluids. This material is also prized for its aesthetic properties, as it resists rusting and other discolorations.
