The ProMation Engineering line of quarter-turn spring return industrial actuators are robust fail-safe actuators for industry. They are appropriately used on dampers and air handling louvers.
The actuators are available in torque ranges to suit most needs. The spring driven rack and pinion mechanism provides failsafe operation during a loss of power situation. They include proportional or on/off control, and responds to a wide range of industry-standard signals such as 4-20mA or 0-10, 1-5, 2-10VDC.
Other features include:
• 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 +125°F (-30°C to +52°C) with internal anti-condensation heater
