12-inch T312 DI Wafer Check Valve SS316 DIS

This 12-inch wafer check valve uses a ductile iron body with a 316 stainless steel disc for corrosion-resistant flow control. It suits industrial and commercial piping systems that need a compact non-return valve between flanges.

Installation and common issues

The wafer design fits between standard flanges so no separate flanged ends are required, reducing weight and space in the line. Ensure the disc swing direction matches the flow arrow and that flange faces are clean to prevent leakage or disc binding.

Compatibility checks before ordering

Verify that the pipeline nominal size is 12 inches and that the flange class matches the valve pressure rating. Confirm the process fluid is compatible with ductile iron and 316 stainless steel, and note the Proposition 65 warning for regulated environments.

Questions about this item

How can I confirm the 12" T312 DI wafer check valve is functioning correctly after installation?

Verify flow direction matches the arrow on the body, check for leakage at the wafer faces under system pressure, and ensure the SS316 disc swings freely without binding.

What components are included with the 116-239 valve and what must be sourced separately?

The valve ships as a complete wafer-style check valve; flange gaskets, bolts, and piping are not included and must be purchased separately.

Which specification should I match when selecting between available versions of this valve?

Match the 12-inch nominal size, T312 ductile-iron body, and SS316 disc to your piping class and fluid compatibility requirements.
