6" T-312 DI Wafer Check Valve

The Legend Valve 116-236 is a 6-inch wafer-style check valve constructed with a ductile iron body and 316 stainless steel disc. It is designed for installation between flanges in piping systems requiring backflow prevention. The unit suits industrial, commercial and agricultural fluid-handling applications where a compact non-return device is specified.

Ductile iron body with 316 stainless disc

The ductile iron body provides structural rigidity for flanged connections while the 316 stainless steel disc resists corrosion from aggressive media. This material combination extends service life in water, chemical and process lines compared with all-iron internals. No actuators, springs or electronic controls are included; the valve operates purely by flow differential.

Wafer pattern limits orientation and pressure

The wafer design requires precise centring between companion flanges and relies on flange bolts for retention, so it cannot be used as a union or end-of-line stop. Installation is restricted to horizontal or vertical-up flow to ensure reliable disc seating. The valve carries a Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How often should the 316 stainless-steel disc on the 6" T-312 wafer check valve be inspected for wear?

Inspect the disc and seat at least once per operating season; replace if pitting or erosion is visible on the 316 stainless surfaces.

What pressure limit governs continuous duty on the 6" T-312 DI wafer check valve?

The ductile-iron body and 316 stainless internals are rated for the full 312 class working pressure during sustained flow.

Does the 6" T-312 wafer check valve generate noticeable noise or heat when left open all day?

The swing-check design runs silently with no moving parts under steady flow and produces no measurable heat rise.
