Control Valve Characteristics: globe_equal_pct to globe_cage_guided_NPS1_linear_port1p3125
Control valve sizing coefficients and ISA-75.01 characteristics — Cv, FL, xT, Fd, rangeability, and inherent characteristic for globe, butterfly, ball, and rotary control valve types. Includes both generic type-level factors (ISA-75.01) and size-specific tabulated values from Fisher Control Valve Handbook 6th Ed. (Tables 5.10.1 and 5.10.2) for cage-guided and Micro-Form globe valves (NPS 1/2–8), V-Notch ball valves (NPS 1–16), and high-performance butterfly valves (NPS 2–16) at 60-degree and 90-degree opening.
