Ball and Plug Valves

Ball Valves

Swagelok ball valves keep system fluid where it belongs, control fugitive emissions and leakage, can be used in a wide range of applications, from general purpose to critical-service applications, and are offered in high flow and quick-quarter turn manual or pneumatic actuation. They have been engineered for repeatable, leak-tight shutoff, have low overall cost of ownership, and can be manufactured or configured to a wide range of specifications.

Offerings include full-flow, one-piece instrumentation, three-piece process, trunnion-style, and multipurpose (for alternative fuel service or general service) ball valves.

Quarter-Turn Instrument Plug Valves

Plug valves are an economical, reliable alternative to ball valves with dependable low-torque, quarter-turn operation. The simple, compact design delivers full flow and positive shutoff and is available in a variety of materials, including stainless steel, brass, and lightweight PFA.
