6. T 51 PRODUCT DESCRIPTION Beck Group 14 linear control drives are engineered for precise reliable operation of globe valves requiring up to 4 000 Ibs of thrust The cool stable operation of Beck s control motors coupled with the powerful gear train provide the tight responsive control required by modern control loops to keep operating costs low The motor can withstand occasional accidental stalls of up to four days without failure and will resume instant response to control signals immediately upon removal of the condition Mechanical stops on the output shaft prevent over travel An easy to turn spoke free Handwheel is incorporated into the Group 14 design to allow manual operation during installation or power outages The Handwheel can be used to open and close valves smoothly and easily under full load conditions The Beck Tight Seater coupling is a part of the Group 14 linear drive This preloaded disk coupling is mounted on the drive output shaft and provides positive seating of the valve plug up to the rated thrust of the drive It eliminates high pressure leakage which can cause erosion of the valve seat A patented self locking mechanism holds the drive output shaft in position when the motor is deenergized A Calibar index allows simple single point adjustment of the length of the stroke to match valve requirements When this adjustment is made the position feedback signal end of travel limit switches and
