  • Patented L-motion link and dual shifts without springs in the actuator enable faster, smoother actuation with significantly reduced vibration
  • Dust seal on the vacuum side of the bonnet flange that virtually eliminates particulate from entering the bellows
  • Mechanical locking so at the end of gate travel the valve locks into position
  • Welded bellows actuator seal
  • Bonnet flange bolts are designed with retainers to eliminate bolts from falling out upon disassembly
