The valves working pressures range up to 3,000 psig (206 bar) and temperatures between 65 to 300°F (53 to 148°C). The single-piece design and live-loaded packing reduces the need to adjust packing and improves thermal-cycle performance. Valves come in two-way straight or angle patterns for on-off service or three-way valves for switching service with end connections in sizes from 1/16 to 3/8 in. and 3 to 8 mm.
