Non-Spring Return Actuators - Promation Engineering

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.
