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 3000 psig (206 bar) and temperatures from -65 to 300°F (-53 to 148°C). Features include a single-piece, patent-pending encapsulated packing design and live-loaded packing system that reduce the need for packing adjustment and improve thermal cycle performance. Constructed of modified PTFE, the single-piece, packing does not require system pressure to seal, reduces potential leak points, and allows bi-directional flow. Choose from 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 3/8 in. and 3 to 8 mm. The valve series accommodates a wide range of handles and actuators. Choose from lightweight, compact rack and pinion pneumatic actuators; ISO 5211-compliant rack and pinion pneumatic actuators; or electric actuators, available in alternating and direct-current modes.
