iVS ACTUATOR

iVS range electric actuators are designed for quarter-turn operating applications requiring a fail position upon loss of power supply. They utilize a compact mechanical spring set to fail the valve or damper clockwise (CLOSE) or counter-clockwise (OPEN).

KEY FEATURES
  • Output torques ranging from 50 N•m (440 lb•in) to 260 N•m (2,300 lb•in)
  • Enclosures meeting the sealing standards of CSA and NEMA Type 4X along with IP67 Ingress Protection
  • Optional Clutch-less Geared Manual Handwheel Override
  • TWO POSITION, ON/OFF or Modulating Control
