Notes

Manufacturer reserves the right to modify dimensions, materials, or design. Contact factory for certification

The Sure Flow Horizontal Swing Check Valve has a cast iron body, cover and disc. The valve is provided with a bronze seat ring and bronze disc ring.

Bronze being softer than a cast iron facing, it offers a more positive sealing effect than competitors’ standard iron facing.

At the same time, a bronze seat ring and disc ring is very versatile in its stability to temperature and various commonly handled materials.

Conforming to MSS SP-71
End Flange Dimensions: ANSI B16.1
