Plastic Electric Actuators

Series 94 Quarter Master

The Series 94 electric actuator is a basic electric actuator designed for smaller (generally up to 4") quarter-turn valves, and is a good low-cost alternative to larger electric actuators. The Series 94 actuators have a thermally protected, bi-directional, capacitor run motor with a permanently lubricated gear train. Because of their size, the Series 94 actuators have a short open/close time, approximately 5 seconds, and a weight of only 3.5 lbs.

  • Motor: Reversing, brushless, capacitor run 120 VAC  50/60 Hz, single phase
  • Overload protection: Integral thermal overload protection for motor windings with automatic reset
  • Gear train: Permanently lubricated
  • Corrosion resistant housing: Zytel FR50 engineered resin with stainless steel trim
  • ISO mounting configuration
  • Conduit: Two 1/2" NPT conduit entries to eliminate cross feed between control, feedback, & power signals
  • Position indication: Highly visible position indicator for positive position of valve, even at a distance
  • Declutchable manual override: Push down on handle and rotate in the appropriate direction (CCW for open, CW for close)
  • Limit switches: Standard end of travel limit switches can be used for light indication (not to be use with PLC for position confirmation)
  • Corrosion resistant mounting: Mounting is with PPG or stainless steel bracket, stainless steel coupling, and stainless steel hardware
  • CE compliant motor: All 120 VAC and 220 VAC motors are CE compliant and stamped as such
  • Extended duty cycles: Our extended duty cycles are ideal for modulating and high cycling applications
  • Output torque: Series 94 Electric Actuators have an output torque range from 150 in/lbs to 300 in/lbs
  • Enclosure: Type 4X
  • RoHS compliant
