4" (DN100) Arita Dual Plate Wafer Check Valve – Class 150, Cast Iron Body, Stainless Steel Trim, NBR Seat, RF

The Arita 4" Dual Plate Wafer Check Valve is a space-saving, high-performance solution for preventing backflow in pipelines. Designed to meet ASME Class 150 standards, it features a rugged cast iron body and stainless steel internal components for strength and corrosion resistance.

This dual plate swing-type valve offers quick, responsive closure to reduce water hammer and pressure drop. The wafer-style design allows for easy installation between RF (Raised Face) flanges. The soft NBR (Nitrile Rubber) seat provides a bubble-tight seal, making it suitable for water, HVAC, and general-purpose industrial fluids.
