3-Way Switching

The original 40 series and the 40G series valves provide various actuator, flow path, and handle options. They are designed for ease of packing adjustment while remaining inline. The 40 series one-piece instrumentation ball valves have operated reliably in multiple industries for nearly 40 years. Swagelok has improved the valve structure and developed innovative assembly processes resulting in the 40G series, which features higher operating temperature ratings, greater thermal cycling capability, and reduced potential for leakage.

Interchangeability

Do not mix/interchange Swagelok products or components not governed by industrial design standards, including Swagelok tube fitting end connections, with those of other manufacturers.
