6" (DN150) Arita Dual Plate Wafer Check Valve – Class 150, Cast Iron Body, Stainless Steel Trim, NBR Seat, RF

The Arita 6" Dual Plate Wafer Check Valve is engineered for efficient backflow prevention in industrial piping systems. Built to ASME Class 150 standards, this valve features a robust cast iron body with stainless steel trim components for enhanced corrosion resistance and long service life.

The dual-plate design allows for quick and stable closure, minimizing water hammer and pressure loss. Its wafer-style body fits snugly between RF (Raised Face) flanges, saving space and simplifying installation. The soft NBR (Nitrile) seat ensures tight shutoff, making it suitable for a wide range of applications including water, HVAC, and non-corrosive process fluids.
