The new Swagelok® 40G series one-piece instrumentation ball valves are for use in environmental applications where outdoor ambient temperatures fluctuate, as well as in heated-process applications with elevated process fluid temperatures. The valves feature working pressures up to 3000psig and temperatures from –65 to 300°F. Existing applications include the oil and gas, chemical, petrochemical, power and other general industrial markets and further applications are expected from laboratory analysis and in pilot plant facilities operating at high temperatures and from industries whose operations face wide ranges of temperature fluctuations. Features of the new valve include, a single-piece, patent-pending encapsulated packing design and live-loaded packing system. Constructed of modified PTFE, the single-piece, packing does not require system pressure to seal, reduces potential leak points, and allows bi-directional flow. Choices include 2-way straight or angle pattern valves for on-off service or 3-way valves for switching service with end connections in sizes from 1/16 to 3/8in and 3 to 8mm. The 40G valve series accommodates a wide range of handles and actuators.
