FCT Eccentric Rotary Plug Control Valves

FCT Eccentric Rotary Plug Control Valve – Robust Control for Severe Service

FCT  eccentric rotary plug control valves are built for demanding process applications requiring tight shut-off, low wear, and precise throttling. Featuring an offset plug design and rotary motion, these valves combine the benefits of globe-type control with the torque efficiency of quarter-turn valves. Ideal for slurry, gas, steam, and corrosive fluids.
