8-inch T-312 ductile iron wafer check valve

This 8-inch wafer check valve uses a T-312 ductile iron body with a 316 stainless steel disc. It is designed for pipeline flow control in irrigation and grounds-maintenance systems. The wafer pattern fits between standard flanges for compact installation. Buyers who need a different body material or a larger nominal size should look elsewhere.

Flange compatibility and orientation

Verify that the mating flanges match the wafer bolt pattern and pressure class required by your piping layout. Confirm the flow direction arrow on the body aligns with the system design before tightening bolts. Ensure the disc has full clearance to swing open without contacting adjacent pipe or fittings. Installers without the correct gasket dimensions should obtain them separately.

Ductile iron body with 316 stainless disc

The ductile iron body provides structural strength for buried or exposed service while the 316 stainless steel disc resists corrosion from water and common treatment chemicals. The wafer profile reduces weight and space compared with flanged alternatives. A Proposition 65 notice applies because the product contains a listed chemical. Workers should follow standard handling precautions during installation and maintenance.

Questions about this item

Does the 8 inch T-312 DI wafer check valve come with any gaskets, bolts or installation hardware?

The listing covers the valve body only; gaskets, bolts and any other installation hardware must be sourced separately.

The title shows 116-237 and T-312 — which figure identifies the size and which identifies the material grade?

The 8 inch dimension is the nominal pipe size; T-312 is the series designation and SS316 indicates the 316 stainless steel disc material.

What does the SS316 DIS marking tell me about how the disc will behave in a water system?

SS316 DIS means the disc is 316 stainless steel, giving better corrosion resistance than standard iron discs in potable or treated water.
