Industrial RUB 3"-450-CWP-PN30-MS58

RUB 3" brass ball valve, 450 CWP PN30 MS58, is a full-bore inline shutoff valve for industrial piping. Built with a Ms58 brass body and a brass ball, it features PTFE seats and an aluminum lever, delivering a robust, corrosion-resistant seal in routine process service. This 3-inch valve is rated for 450 CWP (cold working pressure) and PN30 (about 30 bar), making it suitable for demanding liquids service, with end connections that vary by model—examples include NPT, solder ends, or female-threaded configurations. In practice, RUB ball valves of this family are used to quickly isolate or regulate flow in water, oils, and other process fluids, where a full-bore opening minimizes flow restriction when the valve is open. The MS58 brass composition (CuZn39Pb3) and PTFE seating are common across catalog listings, with some variants noting a chromium-plated ball for added durability.
