6" T-312 Ductile Iron Wafer Check Valve

This 6 inch wafer check valve uses ductile iron construction with an aluminum bronze disc. It suits plumbing systems requiring backflow prevention in a compact wafer profile. The T-312 model fits between standard flanges for straightforward integration. Buyers needing a different body material or disc alloy should look elsewhere.

Installation and common issues

The wafer design slips between mating flanges and uses the line bolts for retention, so no separate flange bolts are required. Proper centring on the gasket faces is critical; misalignment causes seat leakage or disc binding. Ensure flow direction matches the arrow cast on the body before tightening. Over-torquing the line bolts can distort the wafer and prevent the disc from swinging freely.

Compatibility checks

Verify that the piping flanges match the valve's nominal 6 inch size and pressure class. Confirm the fluid is compatible with ductile iron and aluminum bronze wetted parts. Check that the California Proposition 65 warning aligns with your project's material restrictions. Ensure adequate straight pipe runs upstream and downstream for stable disc operation.

Questions about this item

How do I confirm the 6" T-312 wafer check valve is sealing correctly after installation?

Pressurise the line and verify no back-flow passes the aluminum bronze disc; a tight shut-off indicates the ductile iron body and seat are functioning as intended.

What components are included with the 116-226 valve and what must be sourced separately?

The box contains the 6" ductile iron wafer check valve with aluminum bronze disc; flange gaskets, bolts and piping are not included and must be purchased separately.

Which specification should I match when selecting this valve for my system?

Choose the 6" T-312 model when the line size is six inches and the service requires a ductile iron wafer body with an aluminum bronze disc.
