Swagelok® Multipurpose Ball Valves (SK Series)
Swagelok SK series are multipurpose ball valves that offer low-torque, quarter-turn operation in a compact design, providing positive shutoff in applications up to 6000 psig (413 bar), and low emissions certification per API 624.
Request SK Series Valve InformationSwagelok® SK series multipurpose ball valves provide high flow capacity and low-torque, quarter-turn actuation in a compact design. Created for use in applications up to 6000 psig (413 bar), these valves feature bidirectional flow, flow coefficients ranging from 0.9 to 1.4, a variety of end connections (Swagelok gaugeable tube fitting, NPT and ISO pipe, and Swagelok male VCO® end connections), standard panel mounting capabilities, and field rebuildability with a seal kit. Low-temperature SK series valves are also available, as well as low-E valve certification per API 624.
SK series ball valves have O-ring stem seals that require no packing adjustment and provide leak-tight seal to atmosphere. Spring-loaded PEEK seats provide chemical compatibility and leak-tight integrity in both low- and high-pressure systems. A directional handle indicates flow direction and open/closed position, and a stainless-steel floating ball design reduces wear and extends cycle life.
