FCT Ball and V-Ball Control Valve

FCT Ball and V-Ball Control Valve

FCT Control Ball / V-Ball Valve  – Rotary Control with High Rangeability

FCT Valve’s ball and V-ball control valves are rotary-style valves designed for accurate modulation and high-capacity flow control. Their compact quarter-turn operation, combined with segmented V-notch ball trims, delivers excellent rangeability, low-pressure drop, and reliable performance in gas, steam, and liquid service. These valves are especially effective in systems with dirty, viscous, or abrasive media.
