Table of Contents◗CLUTCH/BRAKES“Air Champ” ®FMCBE WITH INTEGRAL VALVE/LOCKING KEY CLUTCH-BRAKES– MODELS FMCBE 625 & 875The FMCBE with Integral Valvecombines a Nexen Flange mounted,totally-enclosed clutch/brake with asingle solenoid 4-way spool valvemounted directly to the clutch/brakeair chamber. Air pressure is directedto the piston to perform either clutchor brake functions. The FMCBE/I.V.is equipped with Nexen’s Locking Keyfeature. Choose from 2 Models:◗ Bore sizes of 0.625 and 0.875 in.◗ Black oxide coating, Cooling fins◗ Simplified; one product number fora clutch-brake combination, controlvalve and locking key feature◗ Reduced number of air lineconnections for quicker install◗ Shorter air lines for better airpressure◗ Eliminates need for quickexhaust valves.◗ 115 Volt is standard on FMCBE.◗ The Integral Valve is available for12, 24 and 115 volt systems◗ Static Torque up to 325 In. Lbs.(brake) and 290 In. Lbs. (clutch)◗ Overhung Load Cap. up to 292 Lbs.◗ Design Speed up to 1800 rpm.Consult factory for higher speed◗ Flange mounts directly to motorsand reducers◗ Compatible with C-face motorsup to 2 HP◗ Optional Foot Mount is availablefor belt drive applications◗ Optional Input Unit allows you toincorporate pulleys or couplingsinto your application◗ Single, double acting pistonmakes overlap impossible226◗ FMCBE FLANGE MOUNTED CLUTCH-BRAKES, TOTALLY ENCLOSED, INTEGRAL VALVE/LOCKING KEYStandard Clutch-Brake is Flange Mounted.
