RWN 5544AB Brass Ball Valve 4 Inch Inline

RWV 5544AB is a 4-inch nominal, lead-free brass full-port inline ball valve from RWV (Red White Valve). This two-piece valve features threaded ends and a forged brass body built for durability in high-flow piping applications. The full-port bore measures 3.94 inches, enabling near-unrestricted flow with minimal pressure drop. It uses a chrome-plated low-lead brass ball, PTFE seats, PTFE packing, and a low-lead brass stem, with a Dacromet-coated steel handle and a brass packing nut for reliable operation. The valve is rated up to 600 psi WOG (water) and 150 psi WSP, and is suitable for service between 15 and 160 degrees Fahrenheit. Overall length is about 7.56 inches with a top-to-inlet-center dimension of 5.64 inches, defining its inline footprint for 4-inch piping runs. End connections are threaded, making installation straightforward in potable-water systems and general industrial-fluid service where a robust, full-port shutoff is required. This 5544AB model combines lead-free brass construction with PTFE sealing and a two-piece, handle-operated design to support reliable, long-term shutoff in mid- to heavy-flow pipelines.
