Quick Shot

The Gate Valve Electrical Drive (GVED) was recently developed at LLE. The GVED improves safety by removing the air cylinder’s stored energy potential and prevents possible sudden changes in physical location. Although the required power to run the drive is less than 15 mW, the GVED produces 2910 ft-lb of torque. For comparison, a heavy-duty-series 600HP tractor-trailer produces only 1850 ft-lb of torque.
