Apollo Valves CS/CL Series Actuactor & Controls

90 Degree Electric Actuator with Torques

CS and CL electric actuators are split-phase reversing AC motors for standard duty or brushless DC Motors for continuous duty. Eight sizes are available which produce breakaway torques between 150 and 3000 lb-in. They are excellent industrial quality units capable of on/off, fail-safe, and modulating applications. The efficient spur gear drive train is supported by permanently-lubricated bearings making it very secure while eliminating the potential for side loading of the output shaft. Apollo offers as standard a 75% duty cycle AC motor. Continuous-duty brushless DC motors are also available for a range of input voltages. All units are rated for use in ambient environments from -40°F (with optional heater & thermostat) to 150°F (note that units equipped with an internal battery are rated to 130°F).

Hazardous Location Enclosures

The standard enclosures (CS and CL) are rated for NEMA 4/4X (weather-tight and corrosion-resistant). The Hazardous Location enclosures are rated for NEMA 4/4X/7 & 9, Class I, Div 1, Groups C&D; Class II, Div. 2, Groups E, F, & G; Class III.

(CSA) Certifications

Certification by the Canadian Standards Association of either hazardous or weatherproof locations is standard on all CS & CL models.


  • Plug-in connectors for the motor, the brake option, and the heater/thermostat option
  • All connectors are coded to prevent miswiring.
  • Limit switch wires are soldered to the board - no more loose connections.
  • A six-position terminal strip is clearly labeled so it can be wired up in the
  • A field without an instruction manual.
  • Thermal overload protection (AC motors)
  • Dual conduit openings; 3/4” (1/2” with supplied bushings)
  • Visual position indication
  • All aluminum enclosure
  • Captive cover bolts on CS Series
  • Manual override shaft (optional handwheel override with declutch able shaft

Features Include:

  • Switch selector for 4-20mA or 0-10VDC input
  • Switch selector for 4-20mA or 0-10VDC position readback
  • Switch selector for either “fail in place” or “fail to zero” upon loss of control signal (provided input power remains)
  • On-board push buttons to manually position the actuator
  • A “Mode Selector” switch with LEDs, which are used for:
    - ”No tools” pot calibration
    - Setting Zero and span
    - Manually positioning the actuator
  • An adjustable pot for speed control (motor pulsing)
  • An adjustable pot for deadband adjustment
  • Locked rotor protection if the actuator cannot achieve the position commanded by the control signal, it will cut power to the motor. Repeated stalls will not damage the actuator.
  • Reverse-acting operation with no rewiring.
  • Split range operation with no rewiring.
