Non-Spring Return Actuators - Promation Engineering

May 4, 2011
ProMation Engineering P1 Series Quarter-Turn Electric, Non-Spring Return Actuators feature a compact industrial grade design for use with all ball and butterfly valves or dampers requiring torque outputs from 135 to 445 in. lbs., have a self-locking hardened steel drive train for smooth operation, and patented clutch-free manual override for single-handed positioning of the actuator in any situation.

Available in on/off, bump/jog and proportional control (factory installed, calibrated, and tested) models, the actuator’s standard features include an integrated position indicator, two auxiliary switches (rated at 3A 250V Max), an internal low-power anti-condensation heater, and cast aluminum polymer coated housing with two ?” conduit connections that is rated NEMA 4X for safe exposure to high pressure hosing and corrosion resistance.  Proportional control units accept a wide range of control signals while generating multiple feedback signals and are easily adjustable in the field. The actuators are available for 12 VAC/DC, 24 VAC/DC, 120 VAC, or 230 VAC supply voltages, are ISO 5211 compliant, offer multiple mounting patterns (FO3/F05/F07), and are certified to CSA 22.2 standards including ANSI/UL 50 and ANSI/UL 429.

Available options include 0-45-90 degree, 0-90-180 degree and 0-180 degree rotation kits, potentiometer and 4-20 mA feedback, cold weather kits (for operation to -40 degrees F/C), timers, speed controls, single wire control interfaces, local control units and fail safe solutions. All options are factory installed, calibrated, and tested.
