Four inch ductile iron wafer check valve stainless steel disc

Legend Valve

Legend Valve 116-234 4" T-312 DI Wafer CK SS316 DIS Valve

SKU CH-64JB-SV0SB

A 4-inch ductile iron wafer check valve with 316 stainless steel disc for flow control

  • 4 inch T-312 ductile iron wafer check valve fits standard flanges
  • Stainless steel 316 disc resists corrosion in aggressive fluids
  • Wafer body design allows lightweight installation between companion flanges
  • New condition ensures factory-fresh sealing surfaces and full performance
  • California Proposition 65 warning indicates regulated chemical content for compliance awareness

4-inch T-312 Ductile Iron Wafer Check Valve

This 4-inch wafer check valve uses a ductile iron body rated to the T-312 pattern for inline flow control. The compact wafer design fits between standard flanges without a full valve body, saving space in horizontal or vertical piping runs. Installers handling water, oil or compatible chemical lines will find the short face-to-face dimension simplifies alignment and reduces piping stress.

316 Stainless Steel Disc for Corrosion Resistance

The disc is machined from 316 stainless steel, providing resistance to pitting and crevice corrosion in chloride-bearing fluids. This material choice extends service life where carbon steel discs would degrade, particularly in cooling-water loops or mild chemical duties. The disc swings freely on the hinge pin to prevent water hammer while maintaining a tight seal at low back-pressure.

California Proposition 65 Chemical Warning Applies

The manufacturer advises that this product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. No additional accessories, gaskets or actuation hardware are included in the shipment. Installers must supply compatible flange gaskets and bolts separately to complete the joint.

Questions about this item

What does the 4-inch size mean when the valve is installed in a pipeline?

The 4-inch designation indicates the nominal pipe size this wafer check valve is designed to fit within a piping system.

What does the wafer connection type imply for installation between flanges?

The wafer style means the valve body fits between mating flanges and is held in place by the flange bolts passing through the surrounding pipework.

What clearance is needed to mount the ductile iron wafer body between flanges?

The compact wafer design requires only the bolt-hole spacing of the mating flanges and enough gap to slide the valve body into position.
