www.swagelok.com Trunnion Ball Valves—Special Alloy Materials 83 Series �¡ Alloy 625, alloy 825, and SAF 2507™ super duplex stainless steel materials �¡ Working pressures up to 6 000 psig (413 bar) �¡ 1/4 to 1/2 in. Swagelok® tube fitting or NPT end connections �¡ Compact, maximum-flow design �¡ Flow coefficient (Cv) 0.75 to 1.6 �¡ Low operating torque �¡ 2-way and 3-way flow pattern �¡ Panel mounting �¡ Pneumatic and electric actuators available Heavy-duty handle indicates flow direction. Bottom-loaded stem: �¡ prevents stem blowout �¡ enhances system safety. Spring-loaded seats: �¡ provide leak-tight integrity in both low- and high-pressure systems �¡ contribute to low operating torque �¡ reduce seat wear from pressure surges. Trunnion-style ball: �¡ prevents ball blowout �¡ contributes to low operating torque. Important Information About Ball Valves ð® Swagelok ball valves are designed to be used in a fully open or fully closed position. ð® Valves that have not been cycled for a period of time may have a higher initial actuation torque. Pressure-temperature ratings for 83 series valves are based on listed seat materials, fluorocarbon FKM O rings, and reinforced PTFE backup rings. Low-temperature L83 series ball valves are available. See page 3.
