Heat Test White Paper

Features and Benefits

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.

• 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 +125°F (-30°C to +52°C) with internal anti-condensation heater
