Spring Return Electric Actuators: Quarter-Turn PA PD

The ProMation Engineering line of quarter-turn spring return industrial actuators are robust fail-safe actuators for the industry. They are appropriately used on dampers and air-handling louvers.

Features and Benefits

  • Available in torque ranges to suit most needs
  • Spring-driven rack and pinion mechanism provides failsafe operation during a loss of power situation
  • Proportional or On/Off Control – Responds to a wide range of industry-standard signals such as 4-20mA or 0-10, 1-5, 2-10VDC
  • NEMA 4/4X Cast Aluminum Alloy Housing – Resists environmental attack
  • Rugged board design for increased electronic connection reliability
  • ISO5211 Mounting System – No bracket/coupling required for most valves – lower profile
  • Standard Internal Heater and Dual SPDT Auxiliary Switches – Normally not standard on other actuators
  • Manual override for single-handed positioning available on all 4 models
  • Easy-to-see Raised Position indicator
  • Ambient Operating range -22°F to +150°F (-30°C to +65°C) with internal anti-condensation heat
