Jamesbury™ 2” (DN 50) 5RNT top-loading and unloading standard port angle ball valves for tank car applications (AAR no. E079030) The 2” (DN 50) 5RNT angle ball valve is designed for top-loading and unloading of tank cars. Easy to install and to maintain, this type valve has proven to be reliable and give outstanding performance in a multi-tude of applications for over 30 years. The 2” (DN 50) 5RNT ball valve offers the advantages of quick quarter-turn operation, long service life, and easy cycling. It is much faster to operate than multi-turn types of valves. In addition, it is easy to cycle even after being set in one position for an extended period. FEATURES Unique Sealing The superior performance of Jamesbury™ tank car ball valves is achieved by the unique design of the seat. The flexible-lip seats exert continuous sealing pressure on the ball. The seat automatically compensates for wear and for changes in temperature and pressure. In addition, this valve is designed to withstand the demanding service requirements of the railroad industry. Materials 5RNT valves are available in all 316 stainless steel. Other materials are available for special applications. FIRE-TITE™ Design All Jamesbury tank car ball valves have the Fire-Tite design. In the event of a fire resulting in partial or complete destruction of the PTFE seats, a secondary metal sealing surface provides continuous effective shutoff. SPECIFICATIONS Flow Data The 2” (DN 50) 5RNT valve has an installed CV value of 70. CV is defined as the flow of water through the valve in U.S. gallons per minute at a pressure drop of 1 psi.The metric equivalent, KV, is the flow of water at 16˚C through the valve in cubic meters per hour at a pressure drop of 1 kg/cm2. To convert CV to KV, multiply by 0.8569. This CV value is an estimate of the installed flow capacity and considers typical inlet losses. Ratings 5RNT valves are rated for pressures and temperatures well in excess of those that are normally encountered in tank car service. Carbon steel valves are rated from –20°F to +500°F (–29°C to +260°C). 316 stainless-steel valves are rated from –60°F to +500°F (–51°C to +260°C). The pressure rating is 600 psi (41 bar) at ambient temperature. Service Representative stocks of 5RNT valves are maintained by the Neles network of authorized stocking distributors located in key areas of the United States and Canada.
