With a deadband adjustable down to 0.5% and an 80% duty cycle modulating service, Series 1000-X and 1000/S-X actuators provide accurate dependable automation packages.

Here is an example of a Series 1000-X Electric Actuator application.  It’s VSI’s popular Series V Ball Valve with Series 1000-X Actuator.

  • Torque Output Range: 443 in-lb to 22,127 in-lb.
  • Housing: NEMA 4 / 4X watertight, corrosion-resistant, powder coated, robust die cast aluminum.
  • Mounting: ISO 5211 Standard mounting configurations.
  • Electric Motor: 120VAC, single phase, 60Hz totally enclosed, non-ventilated, high starting torque, reversible induction type, Class F insulation.
  • Thermal Overload Motor Protection: Auto reset thermal switch embedded in the motor winding – trips when the maximum winding temperature is exceeded.
  • Auxiliary Limit Switches: 2 x SPDT for Open and Close travel limit – easily adjustable, cam operated.
  • Position Indicator: Mechanical dome type with visible red/yellow closed/open indicator.
  • Terminal Strip: Refer to wiring diagrams for details.
  • Conduit Entries: 2 x 1/2” NPT for power and control wiring.
  • Power Gears: Alloy steel spur gears to final stage aluminum bronze worm sector gear.
