The Danfoss 4201SS2 Check Valve is a 1-inch stainless steel valve that permits flow in one direction and prevents backflow in piping systems. Built by Danfoss, the 4201SS2 offers a compact stainless steel construction for unidirectional flow control in applications where backflow protection is required. With its 1" port size and stainless steel (SS) design, this valve is suited to standard piping connections and environments demanding corrosion resistance.
