3DV Check Valves – ½” to 10”, USA

3DV check valves are robust, non-return valves engineered to prevent reverse flow in critical process systems. Designed and manufactured in the USA, these valves are offered in sizes ranging from ½” to 10” and pressure classes 150 and 300. The body is constructed from high-quality CF3M, CF8M, ductile iron (DI), or WCB carbon steel, making them suitable for a broad range of industrial fluids and gases. Each valve is equipped with a CF8M stainless steel disc for reliable sealing and corrosion resistance. End connections include raised face (RF), wafer, and lug types, offering flexible installation across pipelines. These valves are ideal for applications where flow integrity and equipment protection are essential, including water distribution, oil & gas, chemical processing, and power generation.
